Just tested it and it seemed to work fine.
Just to let you know this system is for feedback for editthis.info in general, and is not for a specific wiki. You might want to send a message directly to the admins of the code_wiki.
The problem is that image hosting ended up being a significant cost in running the service for free and so I had to turn it off.
You can easily use another upload service to add images to, and then just paste the link in your wiki page. This will make it so the image is displayed.

If you would be willing to pay a subscription of $5 per month for 100MB of uploads per month to be added to your wiki, feel free to let me know via the bug tracker (http://bugs.editthis.info).
@Solar Dragon - I am sorry that this is a problem. The cost of maintaining image uploads was too much to handle, and I had to shut it off to keep the free service going. For $10 per month I can turn image uploads on for a wiki and provide 1GB of space.
@Johnny Baby - I don't think their is. Flickr is nice for this since they create multiple sizes of the images for you.
