With JPEG's, the file sizes in megabytes will vary considerably even if
the image size in megapixels is always the same.

The file sizes can vary between ~1300k and ~2800k (1.3 megabytes to 2.8
megabytes), depending on image content. So figure between 45 and 95
shots per card. I'd guess an average image size would be around 1.9
megabytes (it seems to be around 2.4 on my 6-megapixel camera), so 70
might be about a typical number of shots for a 5 megapixel camera on a
128 megabyte card. But remember, with JPEG processing, file sizes can
vary significantly. In one batch I shot last year I had images between
1.6 and 3.4 megabytes, all at the same resolution.
