i really dont know why billion doller iphoto does not do it.
The web and photo's have been synonymous for years, decades even, but like me and digital, we will catch up, eventually.
through a glass darkly...
I don't know if this works on Mac, but it is incredibly simple on my Gateway.

iPhoto will do it when you use "Export".
Not quite free: K Studio Resize
I use it to get collections of jpegs to the same size for my web portfolio.
One thing to keep in mind is that there is lots of software that does not resize images correctly. The problem is that they are not gamma-aware so they alter the brightness of the image by incorrectly assuming that output R/G/B intensities are a linear function of the R/G/B values of an image. When taking the average of a R255 G255 B255 pixel and a R0 G0 B0 pixel in a non-linear color space (including sRGB, AdobeRGB etc.), R127 G127 B127 would not be correct.

I have no idea if iPhoto is correct, but I'd assume it is since the OSX image processing library is.
iPhoto and Preview do it correctly. The entire Quartz imaging pipeline is based on linear values.
However, I'm sure it's bilinear interpolation, which is not "ideal" for either reductions or enlargements. But it is GPU accelerated, and if you're really that picky you should own Photoshop anyway.
I always used iphoto and it did a great job.
