hi

first off you really need to clean up your html code you have css styles in the header that have defaulted there (style1 & style9) plus you have

tags all over the place that can go.

also, 804px is too wide for an 800 x 600 browser take it down to 770/780px

I think that this is messing up because of the padding:15px on the center content, this is pushing the 75% too wide for the 804 main width.

what you can do here is give exact widths to the two columns - since you define an exact width for the whole thing there's no need for flexible layouts with percentages. you could give the main content say a width of 550px, plus the 15px padding, then the right content a width of 120px for example. then your pictures will come back to where they should be.

there are people here a lot better at css than me who probably know better ways to do this but this is how i woudl fix your problem.

thanks.
