Since this was apparently not stressed enough, we need to form standards for unit cameos.
For games made up to and before Yuri's Revenge, please use the images from the game files (*icon.shp/*uico.shp) - this content may vary on the game language, and all language versions are welcome (English is a priority). The so-called "textless" cameos from Red Alert 2 and Yuri's Revenge are the own work of tomsons26 and the PreRA2 mod team and as such, we do not have permission to liberally use them wherever possible. Hence, those will be removed.
For Tiberium Wars and Kane's Wrath, there are already transparent PNG cameos available in the main unit article's descriptions. Cropped screenshots of the icons with the GUI backgrounds on are not considered icons and will be removed once all references to them are replaced with the proper assets. Please do not upload any more of these. They are redundant duplicates that look bad.
Removing the small edges in RA2/RA3 icons is more than welcome as long as the rest of the image is undamaged.
Please use the PNG format wherever possible, as JPEG doesn't support transparency and reducing the size adds unwanted artifacts regardless of the quality settings you save them under in Photoshop.
Lastly, do not name them "icons" if there is just one icon in the image.
Oh, and by the way, I'm finally back. Report all inconsistencies and errors (particularly misinformation) to my talk page.
