BLJKE*: I need help uploading a .bmp as a userpic ...
... or at least changing it to a .png, .gif or .jpg!
I have an icon I made with one of those icon-making programs (whose name I can't remember right now). I screen-printed it as instructed, and ended up saving it into a .bmp file (not intentionally, that's just what happened). I really want to have it as one of my LJ userpics, but every time I try to upload it, I get an error message saying that I can only upload images in the .png, .gif or .jpg format, and that the .bmp format is unsupported.
Here's the icon (that I really like):
It really breaks my heart (okay, not really, I'm just being dramatic) to be unable to have this icon as one of my userpics. So can someone please tell me how to change the format and then, successfully upload it? Or better yet, can anyone else change the format themselves? Thanks so much in advance!
ETA: I now have my icon, thanks to silenceleigh, who made it for me just minutes after this post went up. And thank you to everyone else who replied.
