Is there a reason why none of the pictures that I Загрузить ever come out as wallpaper?

Hi, Hans! To put it simple, all Ты gotta do is go visit some site searching for a wallpaper, like let's say Wallpapercave, and then download the Обои to your device (PC, laptop, notebook, tablet, cell phone, или mobile phone, whatever). Just make sure that a file you're downloaded has a tag Обои in its name, или at least wp for short. Then Загрузить that file to Fanpop and Ты won't get any trouble anymore. It's not so much a Вопрос of resolution, and the size in this case doesn't really matter, it's a Вопрос of your file name. Without a tag wallpaper, или wp in the file name, it would always come out as photo. Believe me, been there myself, only couple of months ago, when I was still a newbie on this site, much like you. I just uploaded a bunch of Обои to Charlie Puth Фан club using the same trick of trade. Ты wanna try it yourself? It's so easy. Ты just need to be careful when you're downloading pictures. Any picture without a tag wallpaper, или wp for short, would go to фото by default. That's how this site works. It's not your fault, my friend, it's this Fanpop algorithm which makes it impossible for any newbie like Ты to Загрузить Обои properly to any Фан club on this site. Hope this helps. If not, let me know, okay? I'm only a mailbox away, my friend, and I'm always there for you. Even right now, when I'm drunk at some party on Saturday night with my friends. No, wait, it's already Sunday! Time sure flies, when you're having fun... And when you're drunk, like me, right now. So, what do Ты think of my answer? Not bad for someone who's been drinking all night.

Do they fit the Обои standards exactly, или are they just larger than the minimum stated? I know that they have to be a set of exact sizes, but I don't know what those sizes actually are. The same thing happens to me regularly - it's annoying.
