Sure you want to load up your site with great photos, but try to compress your images so that you can maximize the disc space on your website.
If using a digital camera or a scanner, you should have some kind of imaging software that came with it to help adjust the DPI size. If you can't locate your software, the best free download I've found is called Irfanview. As an added bonus, you can also use Irfanview for resizing images (changing the height or width of your photo or image) prior to upload if you wish.
You will need to edit and size the images before uploading them to your site. For best results use a 72 dpi setting. Typically, a 300 dpi will create a very large graphic file even if the image is small.
For example a 1 x 1 inch image at 300 dpi would be about 270k as where a 1 x 1 inch image at 72 dpi would be only about 4.3k - obviously a big difference that can ultimately save you tons of site space!
