I do not claim anywhere to be selling licensed merchandise and search very hard to find images that are not copyrighted. A lot of these images are used by other sellers on ebay selling similiar items as well ( don't know if that's coincidence or they also search for non-copyright images). I then put in a lot of time and effort to make these images not only suitable but for use on the items they are being printed onto, but also look good as well.

I copied the One Direction photo from a 'backpack' you have listed.  I then cropped that photo and uploaded it into a reverse image google search.  I found that that image has been used in a lot of places on the internet.  I also found that that image was taken by John Urbano (who appears to be a well know photographer).

Take a look at http://www.flare.com/blog/post/63100 where the photo has the John Urbano credit immediately below it

and, I also found the image on this page http://www.billboard.com/events/one-direction-coming-to-saturday-night-live-1006434352.story#/events... where the photo has the John Urbano credit immediately below it.

So, I am only guessing, but I would say that copyright of that image rests with John Urbano and to use that for commercial gain would require his permission.
