I made a awesome skin and i decided to upload it to planet minecraft.

Every-time i click the save button when you select a file it says 'There was a problem loading this media item' .
Now, the skin is perfectly fine, all in proportion, etc its just not letting me upload.
I even tried adding a picture to this post and guess what it said: 'There was a problem loading this media item'.
Any help would be much appreciated.

Extra details: my web browser is Google Chrome and i made the skin on minersneedcoolshoes.com
I also have no problem putting the skin on my character and it works perfectly in-game.
