Safari always reloading page

Oct 6, 2008
I just got my new G3 last week and put Safari to the test. I'm completely new to the iPhone or Ipod and iTunes. I build houses in Second life and like to surf for textures while on the train. I knew that such activity on a phone would be slow, but this is what I'm experiencing:

1. I go to a page with 40+ thumbnailed images and wait ~5 minutes for them all to load. (I expect the delay)
2. I click an image, which invokes a new page and wait for the texture to download. (Again, expecting the delay)
3. I save the texture in my phone and close the page.
4. The original page scrolls back over - the one which contains all the thumbnails....

But then it goes back to the server, reloading the page and and all the thumbnails again, so I have to wait another ~5 minutes for all the thumbnails to reload again.

Is there anyway to stop Safari from automatically reloading to the server?
Thanks in advance
