If you haven't already got it, download GraphicConverter.

With each image that you view, you can see the JPEG compression ratio (in
"picture>show information") which will probably show different settings for
the different images that you have seen.

The level of compression varies depending on what the camera manufacturer
has set as the default. My 3.3mp Sony has a lesser compression ratio
default (bigger file sizes) than the last Sony Mavica I had.

When saving JPEG files in GraphicConverter, you can specify the compression
ratio which ranges from 1:7 (100%) to 1:22 (75%) and so on. By specifying
say 25% (1:41), the file goes very small but ends up a pixelated mess - just
like in a cheap camera (!).

Another major factor in the file sizes can be what is actually in the
pictures - complex (grass with many shades and details) allows a lot less
compression than a shot of a white wall !

Hope this has been of some help/interest

Regards

Mark
