thanks for the links and the info.
I had Commit to Serenity at 1920 x 1200 I droped it to 1200 x 750 and put it in a zip file
for Falling Light I redid the zip to Falling_Light and droped the preview from 1920 x 3636 to 1200 x 2273
thanks for your help...
@ musicislife1995 from what I did and was able to upload I would have to say yes it is resolution related
also try the other upload link that Ausvet gave it will be the one that you have to hit the NEXT button after Selecting the Wallpapers or what every
