In the past I have used paint to size, Ralph. Working with a percentage reduction is quite a hit and miss system and often time consuming to get file size tweaked in to under 100 kb. Some time back I figured a way to size with Picasa and I can do batches of six to eight pictures at a time if need be. I can size to 800 pixels, 640 pixels, etc. However, pixel size is not a direct link to total file size. The total file size will vary quite widely depending on the content of different photos with a set pixel size. As an example, the moon photo above is only 22.9 kb (very low) as there is nothing in it except blue sky and the pale moon. The exact same pixel size photo with a complex image and a lot of various colors could run 240 kb in total file size. Knowing this, you can see why it is difficult to stay under the low level of 100 kb. The allowance parameters you have over on Red Power are much easier to get along with.
