Hi RK,
At this point in time I don't have much experience with graphics nor have any sites to point you to... however would you be interested in letting me gain some experience. I will be very happy to make galleries for you just for tips and a good reference.
I know HTML, CSS and a little Photoshop, however my main focus has been SEO.
I am a full time webmaster and have plenty of time as to make galleries for you and I could also do some submissions, if you cover the submission software fee... you could pick it up for me if you like or send me a copy so that I could submit for you.
If you would like some extra help creating your galleries please email me at:
