Paul,
If I may suggest:
to further separate/itemize your images by subject in a few of your large folders.
For example:
Your folder - 'Black and White & Toned' (318 images)- I would make it just B&W - "nature" part one (100 images per folder)... then B&W - "man-made or structures" part one (100 images) or some other descriptive title so the viewer can
easily and quickly find what they're looking for before they become overwhelmed. Your sepia / brown toned images should be separated in their own folder.
(I'm only "picking" on your B&W folder because - when I peek at anyone's profile, I immediately take a quick look into their B&W folder/s as those images will tell me more about the
photographer than the color ones.)
If I see a folder labeled - "Nature" and it contains 1738 images! ....I get overwhelmed just by the shear number and move on. I think artists would benefit from separating their works into folders with titles that mimic this website's search keywords. Break up those large folders into more narrow / specific groups.
cheers
Ken.
