Certain image won't upload;don't know why

[MrHippie]

I've been trying to upload this image of "Burning Kirby", which I've attached, and the original file is also available here:
http://kirby.wikia.com/wiki/Burning


Are there certain size requirements, etc etc etc that this picture doesn't meet? I know its less than the 2mb requirement easily,
but there must be some other issue. If anyone knows what it is, and how to fix it, please let me know.
If there's an online list of what's necessary for a picture to upload properly, please let me know, because I looked around the site but couldn't find anything.
Thanks

By uploading the image, and then taking that same image from when the forum hosted the image, and re-uploaded that to the card maker, and it worked like a charm!
So the only difference I can find between the two images is that the original is a jpeg, while the new one is gif.
I'm still curious and would like to know, if there is a set list or outline of what is necessary for the card maker's images.
Sorry I'm still very new at all of this

don't use attachments, save the image as a jpeg first.
I learned the hard way about attachments.
