Yes, I do get annoyed and frustrated sometimes when that happens. It doesn't even have to be pictures, it can be videos, links, picks etc. It depends on the situation though. For example if the pictures are HQ or a slight different version, or if the video is an extended interview or an extended artigo with mais information than I don't mind so much. Most of the time I just ignore it and rate it low-ish. We can't do much about it.
Also sorry if I'm an offender on this spot, I don't come on this spot a lot and I check before I add anything to see if it's already been added. But checking can only do so much and everyone makes mistakes.
