''I'm not too familiar with law in general...'
Then I respectfully suggest that you use the internet resources available to you and look up 'copyright', 'public domain', and 'fair use'. If you're feeling really ambitious, try 'DMCA' as well.
I also take photos and hope that people might find some benifit in them.
They are still my photos. I have made them visible to the public, but I have NOT placed them in the 'public domain' by doing so. That is what copyright protection is about.
One of my photos from my gallery here was placed on a website without asking my permission, or giving any indication that the photo is mine, or where it was taken from.
That made it look like the photo belonged to the person that runs the website.
Had the photo at least been attributed to me, I could have shrugged it off as 'fair use' IF I wanted to.
''I browse the gallery here occasionally when someone has question which would be best answered with a picture, and I use other members photos if need be. Is this illegal? If so then the gallery should not be open to the public.''
IANAL, I don't give legal advice.
Anyone tracing the link in a RC picture to a gallery can generally figure out which gallery it came from.
''If you do not want someone else to use your photos then they should not be posted in such a way that anyone can veiw it or they should be copywritten. Just my opinion.''
My photos are by default protected under copyright. If I do not want someone else using my photos in a way that infringes on my copyrights, I assert my rights and tell the site owner to remove my picture(s).
Such as I have done in this case.
I also walk after sundown alone.
IANAL
