1. Go to the page on the wiki to which you would like to add an image or poster.
2. Click the "Files" button near the bottom-right of the page. Some things will appear below the buttons.
3. Click the "Upload a file from your computer" link. Even more things will appear below.
4. To the right of "Select a file on your computer", click the "Browse" button.
5. A popup window will appear. Find the file on your computer and double-click on it. The window should go away and the path to your file should now appear in the text box next to "Select a file on your computer". You can optionally change the name of the file and add a description, but these are not required.
6. Click the "Upload" button and wait a little while as the file is transferred to the wikidot server.
7. Once that is done, your file should be listed at the bottom of the page. If you don't see it, try clicking the "Files" button again to make the list appear.

Now we know that the file is on the wiki, but it won't appear on any page(s) until we add a link to it. First, we'll show how to link to a generic file type, such as a pdf for a poster. See below for the case where the file is an image to be displayed.

1. First, make a note of the name of your file. Let's say it is myposter.pdf, for example.
2. Click "Edit" to edit the page as you normally would.
3. In the editor, find the place where you would like the link to appear, and add a tag like the following:

[[file myposter.pdf | Click here to see the poster]]

Note: The part after the "|" can be whatever text you want to appear in the link.

For instance, if you were adding this to the standard table that appears at the top of an event page, the code for the new table row would be:

||~ **Poster** || [[file myposter.pdf | PDF]] ||

Alternatively, if the file you uploaded is an image, say myimage.jpg, you can display the image with the following code:

[[image myimage.jpg]]

Hope that helps.

How do I upload a poster to the wiki for an event?
