Ok just a few quick thoughts
1- Read search the net and read as much as you can on SEO... why some people will spend 6 hours a day reading boards and not 5 min. reading how to do a little seo, I will never understand.
2- Read up on PPC anmd PPC software.. Anyone doing PPC should be using some software even if its just to let you know things are working like you thought they would. (ie.
http://www.bidmaximizer.com/)
3- Blogs, Myspace, etc.. read the rules to posting... see what you can do .. seach see what other people are doing... try a few diffrent things and see what works fro you . Once you find something that works make copies..
4- TGP / MGP.. the faster they load the better if your gallery cant load on a slow pc running a 56k connection then it runs to slow (just my thought on it)
Don't get to much away 12-16 pic is more then enough.
Anything that gets you 50 hits a day that you can copy 100 times will get you 5000 hits a day. its all just how much work yo uwant to put into it.
What ever you do give it some time see whats working remove whats not and repeat what is.
