I see you have a Bravehost site. At the moment, Bravenet offers two deals:
Free hosting: 5 megabytes of webspace.
Premium hosting: 30 gigabytes.
Are you stuck with a longterm deal from the old days?
Anyway, you can probably save a lot of space. I see you have this photo gallery, where you can click a 65x65 pixel thumbnail to see a larger, 231x196 pixel version. And that should be it, for most visitors. Unless it occurs to someone to rightclick the big image and select "Open image in new window". Then you get to see whatever tiny part your screen resolution allows of a 3280 x 2460 pixel, 1.4 megabyte image! That is about 6 times the size of the screen I'm using right now. There is no reason to display that image on the web using more than 70 kilobytes. That is if you are using a whole page. The way your simpleviewer displays them, 7 should be enough.
