HELP!!!!

I have been trying for so long to upload a cover image for my fics and have had absolutely no luck!

So much so that I am asking for help through a blog lol *face palms*

So I have been trying by uploading the images on to other sites and have no luck and I even tried uploading the image to tumblr and tried that way. Even using the embeded code and nothing is working for me :((

Please help a author in need lol ^^
