Both pictures are 776x582. The top one is 118K & the bottom one is 190K. Why can't I make them so they're the same size here, and why does the top one (technically the smaller one) always appear bigger?
Nice pics. I was up at the park several years ago (I think my 30 year old son was about 12 - damn!)

Anyway, to answer your question - It's has to do with the way the compression algorithm works. If you have a large picture with the same or similar colors and areas, it's going to be smaller than a small picture with lots of complexity in it. The simplest explanation is to imagine a picture with no detail and all one color. The algorithm only has to record the one color and a repeating pattern (i.e., where do I start this color and where do I stop it), while a picture of a complex mosaic, say, has to not only have the multiple color information but also a lot of repeating and position information in it. Your second picture is much more complex than your first one. This is oversimplified, but you should get the idea. Hope that helps.
