At work, I accept GIF or JPG images as branding logos for creating billpay websites. (No PNG for political reasons.) But this one Project Manager has been sending me empty GIFs for weeks now. As in, Outlook even says “0 bytes.” She doesn’t understand why I reject them, even after I tell her that the image files have no content in them. It’s very frustrating trying to make people understand that zero bytes means “no content.” Gah. Then again, they’re SUPPOSED to be previewing these files before they pass them on to me. That hasn’t ever happened.
