Please help me. I honestly don't know what is wrong with WordPress. i've tried to upload my header picture in SEVERAL THEMES, different browsers, different sizes, different optimization, different computers, and none of them work. Please help me fix this problem. I seriously don't know why WordPress has been so hard to use....but it's been horrible because I can't even get started. Please help me figure out what is wrong.
