hello! i am just confused.

first.) are the wallpapers i upload to zedge automatically categorized according to my device type or according to the resolution of the wallpaper i upload? my wallpaper resolution is 640*480, are other phones with the same wallpaper resolution able to view my uploads? or just phones same as mine?

secondly.) if i upload a wallpaper with resolution in accord with the wallpaper resolutions of other phones but not my registered zedge phone, will those other phones "see" it? for example, i made a wallpaper with the resolution specific for galaxy s3, will galaxy s3 phones see it even if i uploaded the wallpaper with my xperia phone still registered in zedge?

thanks for the answers ..
