I'm trying to post a pic from Subeta HQ from the HA generator and I can't upload it any where says it's the wrong format, what can I do?

Where are you trying to upload it to? o_O; Unless you just mean posting on the forums, the code is

[img]URL[/img]

without the *s, of course

Yes I did all that but when I try to upload it on tinypic it says Upload Failed! Uploaded 0 of 1. Invalid format (jpg|bmp|gif|pcx|png|psd|tif)

Maybe your not saving it as jpeg or something?
