# Images

To upload the main image for your page, use the upload button inside the Create an Image Page form, which you get to from the sidebar. When you access the form, it looks like this:

Click the Upload a Math Image button. That brings up a pop-up window that looks like this:

First click the Browse button and find your file. Then click the Upload File button. Fill out the rest of the form, press Save Page, and your image is up!

To upload other images, use the Upload a File form, also located in the sidebar. It's essentially the same form as in the pop-up window from the Create an Image Page form. Click the Browse button, find your file, and then click Upload File:

You might also want to use the Summary box to put in image credits, although you can also do that after the fact.

## Inserting images in your page

The basic code you use to put an image in your page is:

```[[Image:FILE_NAME.gif]]
```

Where you replaceFILE_NAME.gif with the name of your file.

You can add extra things to the image tag to make your layout nicer. To re-size your image, you add NUMpx, where NUM is the the width you want for your image. This tag would makes the picture 500 pixels wide:

```[[Image:FILE_NAME.gif|500px]]
```
This image uses lots of fancy formatting.

To align an image, you use center, left, and right. The tag below will make the image be on the right side of the page, your text will wrap around it:

```[[Image:FILE_NAME.gif|right]]
```

If you want to add a caption to your image, you can use frame or thumb. Frame doesn't allow you to re-size the image. Even if you put the code for re-sizing in, it just won't work. Thumb lets you re-size the image.

```[[Image:FILE_NAME.gif|frame|Your caption goes here.]]
```

The following tag combines the above options, and produces the image shown to the right.

```[[Image:Elephant.jpg|right|thumb|250px|This image uses lots of fancy formatting.]]
```

Instructions for how to do linking image tags in text and in captions, as can be seen in the pages Quipu and Basic Trig:

There are three parts to making these tags.

Creating the anchor. This is the spot on the page that the links will jump you to - it doesn't have to be an image, but that's the application of this code we're focusing on. Right before your image code, type:

```<div id="NAME"></div>
```

This name should be something you will remember. It won't show up on the page, but you will need to use it later in the code. It can be something simple like Image1, but it can also be more descriptive, like trianglepic. Make sure there's no text or empty space between this code and your image - you can even put the "</div>" after your image if you want.

```[[Image:FakeImage.jpg|frame| [[PageTitle#NAME|Image #]]. Any other text you want in the caption. ]]
```

Obviously, you need to replace FakeImage.jpg with your image's filename, PageTitle with the title of your page, NAME with the anchor name you used in the last step. Image # is what the link will look like - so replace the # with whatever number you want, or, if you want to call the whole thing something else, you can do that too.

Putting a link in your text. This is just like putting a link in your caption, except it's in the body of your text. It should look like this:

```Here's some awesome text that's going to tell you to look at [[PageTitle#NAME|Image #]] for clarification.
```
Again, PageTitle, NAME, and # need to be replaced with what these things are actually called on your page.

# Feedback

Instructions for how to provide and format feedback, including changing font color.

One really important aspect of working on the Math Images Project is providing feedback on other people's pages. Feedback is usually provided using a page's discussion page, which you get to by clicking on the discussion tab at the top of any page:

#### Outlining

As of summer 2011, we decided it would be helpful to give feedback following the same outline as the page. This means that either the page creator or the first commenter should replicate the page's headings on the discussion page (with an extra section for general comments).

 If your table of contents looks like this: …the outline in the discussion page should look like this: ``` =General Comments= =Basic Description= ==Basic Description Subsection== =A More Mathematical Explanation= ==MME Subsection 1== ==MME Subsection 2== =Why It's Interesting= ```

If the page has teaching materials, you'll probably want to include that section too.

Once the outline is created, everyone giving feedback should try and follow it.

#### Timestamping and color-coding

It's important to be able to tell who left each comment, and when. One way to help with this is to use user- and timestamps. The wiki allows you to create these by using tildes. When you write

```~~~
```

the wiki replaces it with your username. For example, when I write it, it shows up as Kate. The wiki replaces the tildes in the code for the page too, so if you look at this section you won't see them, but trust me, that's what I wrote. Four tildes gives you your username and the current date and time (using the UTC timezone):

 ```~~~~ ``` Kate 17:19, 22 July 2011 (UTC)

Putting a timestamp at the beginning or end of every comment you make will make it much easier to tell where comments came from.

Another way to make it easier to identify comments is for each person to choose one color to make all their comments in. The code to change your font color is:

```<font color=COLORNAME>This text will come out whatever color you put in for COLORNAME.</font>
```

For example, this text is blue.

Make sure to close your font tags! You don't want to make the whole page colored! Also, be aware that if you're using bullets, this code:

```*<font color=COLORNAME>First point
**Subsequent point</font>
```

doesn't work, the rest of the page will be whatever color you wrote in the tag. In general, put your font tags on their own lines to make sure that they start and end where you want them to.

A list of all of the color names that are supported in the wiki can be found here.

# Balloons

Instructions for how to make balloons.

Balloons are really handy for when you want to use a term that not all readers may be familiar with. You can put the definition in the balloon, and readers who don't know the word can find out the definition without you having to upset the flow of your sentence. The code for a balloon is pretty simple, it looks like this:

```<balloon title="This is the stuff that shows up in the balloon">Balloons are fun!</balloon>
```

That code makes a balloon that looks like this: Balloons are fun!

If you want to put math writing or images inside your balloon, it's a little more complicated. You need to put the content of the balloon inside a span tag, and then inside the balloon tag, you tell it to load the content from the span. The code for that looks like this:

```<balloon title="load:title of content">I'm a balloon</balloon><span id="title of content" style="display:none">Let's have some math: [itex]x^2 + y^2 = z^2[/itex]</span>
```

The above code produces this balloon: I'm a balloon

You can make balloons that are also links. It will look like a regular balloon - it'll be green and when the reader mouses over, the pop up will show - but when the reader clicks, it will act as a normal link, so you can send them to another page or to an anchor somewhere else in the page. The way you do that is just to add a link field in the code:

```<balloon title="Click to go to the balloon section of the Wiki Tricks page" link="http://mathforum.org/mathimages/index.php/Help:Wiki_Tricks#Mouse_Overs">I'm a balloon AND a link!</balloon>
```
This code makes a balloon that looks like this: I'm a balloon AND a link!

# Hide/Show

Instructions on how to use the two most versatile Hide/Show templates, Hide and SwitchPreview.

There are a lot of Hide/Show templates to choose from on the wiki, but here we'll only be talking about two of them. For instructions on the others, check out Wiki Tricks.

The most basic Hide/Show template is Hide, which looks like this:

```{{Hide|1= This text will be hidden. }}
```

It produces this:

This text will be hidden.

The hidden text can be as long as you want it to be, and it can contain images, equations, and tables.

SwitchPreview, the other Hide/Show template, is more customized. It allows you to change the show and hide messages, and the preview text that shows. The code it is this:

```{{SwitchPreview|HideMessage=Click here to hide the stuff!|ShowMessage=Click here to show the stuff!
|PreviewText=You can leave this blank if you don't want a preview.|FullText=This is the full hidden text.}}
```

That code ends up looking like this:

You can leave this blank if you don't want a preview.

This is the full hidden text.

# Citations

Instructions for how to cite images and other sources.

You don't need to cite general mathematical knowledge, but you do need to cite direct quotations, unique or original work, and all pictures.

### Citing images

If you did not create an image and it doesn't explicitly state that it's free for you to use, you must contact the copyright holder and ask for permission to use the image.

Most images on Wikipedia are free to use - click on the image, and scroll down to the Licensing section to see if you can use the image:

This file is free to use, as long as you link back to the page it came from.

On the file page for the image, you need to state where the image came from, even if you made it yourself. You can do this by filling in the Summary field when you upload an image, or by clicking the Edit tab after uploading and adding it in.

If you made the image yourself, the credit should read something along the lines of "Image created by NAME", where NAME is a link to your userpage. If the image is a free image, a link back to the page you got it is usually sufficient. If you asked and were granted permission to use the image, you should credit it in the manner specified by the copyright holder.

### Citing text

The first time you want to reference a source, you provide all the information, and (if you're going to use this source more than once) give the source a name. You do this like so:

```Here is the fact that I want to add a reference to<ref name=AwesomeSource> Author, A. (1900). Title. Place of publication: Press name.</ref>
```

After that, you can refer to a source by using its name:

```This sentence also uses a fact from my first source<ref name=AwesomeSource />.
```

Finally, in the reference section of your paper, you write:

```<references />
```

All of this ends up looking like this:

Here is the fact that I want to add a reference to[1]. This sentence also uses a fact from my first source[1].
References:
1. 1.0 1.1 Author, A. (1900). Title. Place of publication: Press name.
