The imagination runs, and not in the way you think.
Photos do not in anyway have to download with a URL attached. For this reason, keepers of the copyright of photos will include some sort of "watermark"--such as their name, webaddress,
et cetera, on the photo.
You write the photos:
this was not on my computer.
it was in a folder with other archived pictures, . . .
does that mean they did not
come from your computer but are
on your computer? If not, "where" are they?
Depending on what the photos
are--from a set of pornographic shots to what I will conclude with--depends on what you do. Clearly
you did not download them.
If they are pictures of, say,
you, and you are concerned with the possibility of pictures of
you being on the interwebs that is one matter. If they are something you do not want on your computer--garden variety Star Trek porn--that is another matter.
If they are of, say, of an
illegal nature then you have entered into a far more serious area which, depending on your jurisdiction, incurs upon you legal responsibilities and risks. Let me give you a "fer instance":
What with "kids these days"--with their hotrods, bobby socks, and that "rock and roll!"--have been known to use their iPhones, cellphones, various computer cameras to take pictures of themselves, giggle, and "send them to friends."
THAT, Me Lass, pushes this from personal irritation to violation of state, federal, and international laws.
So, while it may seem we ask out of prurient humorous interest, it would help if you "narrow the field" a bit. What is advised greatly depends on where you are in that imaginative spectrum.
