Best practices for graphics-heavy webpages?

I'm creating a website with several photo galleries. I've compressed the photos as much as I can without losing quality, but most are still around 200-300kb. With a couple dozen of these photos on one page, loading times can be pretty sluggish.

What are the best design practices for image-intensive pages? Should I focus purely on file sizes or are there some design/development tricks I can use? Right now, I'm using slightly smaller thumbnails which link to the actual image through Lightbox. I should also mention this is for a photography portfolio, so I'd like the viewer to see all the images up front rather than one at a time via a carousel.

I'm not sure if you've already seen it but Treehouse has a Technology Foundation course which covers the best practices for saving images for the web - http://teamtreehouse.com/library/technology-foundations

As you have said, loading a smaller thumbnail image and the larger image later is one option. If this is photographs I'd expect jpeg to offer the best compression.

Another option to consider is to host the images elsewhere (e.g. AWS S3) or even use a Content Delivery Network but this might be overkill for a small photographer.
