Transparant PNG creates strange artifacts

If a transparant PNG image is uploaded, it creates strange artifacts after the instructable website changes it's size.
A nice platter of weird colors in the Transparent areas.

Strangely enough if a ridiculous high resolution is chosen while uploading, 1024px wide or more it creates a correct image.
(my best guest is that the image converter crokes on the image size, and does the conversion in the background later on).

You also take your chances on using animated GIFs.

I usually convert PNG to JPG before uploading, precisely to avoid the weirdness.
