Bob, you can change how images behave, by selecting the image, then right clicking. That lets you change the displayed size, boundaries, justification, etc. Here look at this copy of your post where I used a width of 360 pixels (auto height), border of 1, horizontal and vertical spacing of 15 and alternate left and right justifiction. You can still click the image to see it full size.
There is, of course, specialized software available that can automate the process to a degree. "Dartfish" is the program that creates the instant montages you've seen on some television broadcasts, particularly of the Olympics. It makes me sick how quickly and effortlessly it does its thing, but the results I've seen, while looking fine on television, are not of the quality of a hand-made montage. Still, I can't help but envy it! It is not inexpensive.
Good luck! Please post your results, as well as any good "tricks" you come up with.
Here are a few of mine, all of which have been posted here before:
Patrick Deneen, US Ski Team (moguls), training at Mt. Hood last summer; from 35 mm DSLR
Freestyler Sammy Carlson, also at Mt. Hood, from high-definition video
Cyprien Richard (France), Noram GS at Keystone last season, from high-definition video
Me, Arapahoe Basin, 2007, from high-def video
David Oliver at Telluride, from progressive scan standard definition digital video
Dan Egan, Arapahoe Basin 2008, from hi-def video
Ben Atkinson, Keystone A51 Terrain Park, from progressive scan std def video
Me again, Arapahoe Basin, from high-definition video
Toni Sears at Arapahoe Basin, 2008. Note that the camera was zoomed for the last frame, requiring that it be enlarged to match the rest of the sequence, and losing some sharpness. Don't zoom when shooting for montages!

Some of these images have some additional Photoshop work, to fill in the background (mostly through "cloning") and otherwise polish them a bit.
