"... art should not feature screenshots, official artwork, scans, copyrighted photographs, or similar items."Also, just because you credit something doesn't give you a free pass to use it.

If you are tracing something or using it in a collage or photomanipulation, you need to have the permission of the owner/artist to use the image. Upon posting image online, credit must be given to the artist whose art you used. This credit can be a mention in the artist's comments with a link back to original piece and to the artist or the placement of the artist's name clearly visible on the image.
If you are using something as a reference (not tracing) permission is required for use (if not stock art) and then credit given upon posting of art online or elsewhere.
If you are using direct quotes from an author in
anything, credit must be given.
If you are posting doll-makers or other such things, it needs to be placed in 'Scraps' and have a link to original maker.
Note: Many makers do NOT allow you to post your creations to dA. You need to figure out if you can post it here before you post itIf you are posting wallpapers or icons here, be sure to follow the rules listed above because you don't get special privileges just because you are making a wallpaper.
AND IF YOU WANT TO POST AN ORIGINAL OF SOMEONE'S WORK HERE(which includes screenshots, gifs, icons, blingees, etc that contain images that don't belong to you.)You better show
explicit permission (ie: a link to where the artist told you that you could use it) in the artist's comments and then link back to the image you are using and the artist.
