Example image.

On the AoPSWiki, images can be posted as a manner of accurately illustrating a problem/solution or for depicting an article.

Uploading Images

To upload an image, click the "Upload File" link on the toolbar, or just press alt+shift+u, both of which lead you to this upload page. Once there, click the "Browse" button on the side of the first text box, and locate the image from your computer that you wish to upload. After selecting it, then enter any comments into the large text box. It is perfectly acceptable to refrain from entering comments.

Images must not violate copyright.

When uploading an image, try to create a descriptive name for the image. If the image is for the illustration of a contest problem, please note that, with a format similar to YYYY Contest-# (like Image:2007 USAMO-4.PNG, Image:2007 USAMO-4b.PNG). Generally, years or other information related to the contest, in general, should be placed first, followed by the number of the question.

Once the image is uploaded, you should be redirected to the image page. The title of the page should be "Image:Your image name here".


The general syntax for an image is:

[[Image:Example.png|thumb|left|###px|Image caption]]
  • The type is either “thumb”, “thumbnail”, or “frame”. If not specified, no caption or border will appear.
  • The alignment is either “left”, “right”, “center”, or “none”. Left/center/right are self-explanatory. “None” indicates that the image will be on the left and the following text will go down to the next line (as opposed to “left”, in which the text will flow around the image)
  • The size is in px (pixels).
  • The caption should be a brief description of the image, if there is one.

To display the image inline, use the same syntax but leave type/alignment blank, and insert the code into the middle of the text you wish to place it at. To create a link to the image, use a colon; for example, [[:Image:Example.png]].


The syntax for a gallery is:

Image:Example.png|Image caption

A gallery will display several images in table format in a nice looking manner. This is useful to present a large number of images.
