That is not fair. Cause what if they have exclusive rights to use such a photo cause it was given to them by a friend or family member and they do not have the right to distribute it?
I have used several photos as desktops that i have shared with people over the years and when asked i said i couldnt distribute till i got the cleareance.
Sometimes it is a personal work that they dont wish to share on the internet as well. People dont have to divulge sources if they dont want to.
This is my wallpaper, my res is 1920x1080 I brought it down to 1280x720... The background was made by a kid in my computer class with GIMP, yes its dumb but I think it's kind of funny
Dont worry about that mate. I have several wallpapers that i use which were created by my baby in Paint. Just a bunch of lines but i use them cause of who created them.
