What are the specifications for plugin icons?

[philpax]

512x512 png, preferably transparent, preferably looks good when rendered at 64x64

"An icon for your plugin has to be in "YourPlugin/images/" as "icon.png". The icon has to be representative of what your plugin does, ideally have transparency and be at max, 512 by 512 pixels. It will be rendered at 64x64, so try to have it look nice at that resolution."

That's in the readme, probably should link the readme in the faq, unless it already is!
