Unable the adjust the width of the main page

[mikeofthejungle]

The width of the home page is huuuuge, and I'm not sure how to get it to fit on the width of a screen. I'm sure its simply a case of adjusting an option on the config panel but I've been playing and nothing seem to be having an effet. The site can be found at www.mikejeapes.twzone.net, if there's any other info you need let me know. I've tried searching this problem for 30 minutes but can't find anything else. Also I'm not that great with computers so small words would be appreciated, many thanks!

Apologies, I've solved it myself. For future reference:

Size in pixel of the thumbnails is not refering to the picture itself, rather the space on the page dedicated to it. If you set a large space for the thumbnails you're going to have a large page
