What I am wanting to do, on my web page.
Is have a smaller photo, and then being able to click the photo and another page open up with a full size photo on it.
I want to be able to put 8-10 "see-able" thumbnails on a page at once
What would that size be?
Well if you keep in mind that most users only have 1024 x 768 screens then you are limited to about 200 pixels or so to still have some space around the thumbnails. On my Pbase account (link in my sig) they use 160 as the max. On my 1024 x 768 screen at work that shows 3 rows of 3 thumbnails. I could extend that to 4 rows of 3 but I haven't just yet.
