damn , since 3 days i've already deleted 4 different ugly custom covers for this fu**** game !!!!!!
rules are in place , minimal size for hq covers is 1024x680 , but if someone convert a 512x340 to 1024x680 before uploading , all we can do is delete it.....
the upload form is not , and will never be able to judge itself the quality of the cover that is uploaded ^^
