Here is a zip containing an example broken image. This one is broken in a less common way than others (which is generally an incompatible color format or a sizing issue. This one is an issue with the transparency encoding).

Open the zip, and try to upload it.

For reference, I'm attaching that image to this post. It should be absent, unless endchan has changed something recently.

Also attached is a screenshot of me attaching blahdeblah.png
