The navigation buttons are available on all pages. Icp.html Software is organized in separate pages. This saves download time due to the size of the screenshots. The screenshots are in JPEG format to save download time. For these images, the format is good, though.
All pages have the same navigation to keep the same feel throughout the site.
Each page is seperate to let the user view each page separately, so that all graphics do not have to download at once. A person looking for on particular type of software does not need screenshots or info of another product, plus it clutters the page. The first page is as always, kept simple. Text links will do, flashy graphics are unneeded at this point. All pages have the same or similar graphics to keep with the flow.
