Out of memory.

[iplanit]

After reading the many posts relating to the "out of memory" issue I am setting up by photo gallery website in sections. My first site is my "index" file with the home page, the galleries are all there own "sites". I have exported and published all to the appropriate place on the server. Set up links as relative to url's. All appears to be working fine. But, is this really the best way to do this? Should I be putting the gallery "sites" in a different place on the server instead of where I publish the home page? Linking to a gallery looks like this...www.******.com/gallery1.htm. Mysite the main "site". Gallery 1 is it's own "site". I am a total newbie! I use Windows 7, and have 9GB ram. Should I really be running out of memory? Thanks!
