Hmm:
If someone takes a photo, copyright can exist in that photo. If someone takes a photo of a work protected
by copyright, and the work forms an essential part of
the image, using that photo on the web is likely to be
an infringement of copyright. In other words, people
are allowed to take a photo of a room of paintings, provided the inclusion of such paintings in the photo was merely incidental (for example, they formed inessential background). However, you would need to be careful about copyright infringement if taking photos of specific paintings.
I would argue that in my case the clothing logo is merely incidental to the purpose and intention of the photo. But I don’t know if a copyrighted work and a trademarked logo differ in how they’re treated?
