I created an image that I want to use as a sig on the website (i know, i do it all the time, but this is the first one on my mac). i saved the image for the web as a JPEG, and then went to upload it onto photobucket. but photobucket won't let me upload it. when i'm browsing my documents, the image is there, but its icon and filename are opaque and i can't click on it. so i tried just normally saving it as a JPEG, and exactly the same issue. what's going on here? i really want to use this sig!
