Thats a damn good quick start that for something has been asked for a cover for years!
I think in this case the thing has been that the front image has been so bad that nobody has bothered to do the cover.
Whipping up a temporary cover from ready material (including that the back text has been already typed so simple copy paste) and ready screenshots takes minute or two.
What font do people use for the backs?
Arial I believe is the most used.
Also, I can never get uploading images to work. Just appears a small image box icon. Any help?
From box you can't so you need to use additional image sharing site like imageshack or photobucket (which are not suitable for actual cover sharing) for the preview.
From Mediafire you can directly do sharable images like the ones we used.
Just click share -> More sharing options -> Choose Embed Size (I use 17" monitor option usually) -> copy the Forum Embed Code -> post it here as is (no additional tags or such needed..
