Actually Adobe Photoshop Elements does a really good job of scaling pictures via its "export" feature. I use a couple of different Canon cameras, a 30D which has a aspect ratio similar to APS film cameras, and a Powershot 700 which has a 4:3 ratio. I group my pictures in "albums" within Elements, then select the Album, select all photos in the album, hit "export", and then set it for "jpeg", custom resolution of 800 x 480, and a directory and common file name (which it then numbers sequentially afterwards). The pictures scale beautifully and instead of 2-3+MB files nearly all are less than 100K. The beauty is the export feature doesn't screw up the aspect ratio even though I may have pictures from two different cameras in the same album - it simply uses the maximum value within my setting and then scales appropriatly the other dimension.

Example: A picture from the 30D has a resolution of 2160 x 1440 - the scaled exported picture ends up with a resolution of 720 x 480 (maximizing the vertical resolution).

A picture from the SD 700IS has a resolution of 2816 x 2112 - the scaled exported picture ends up with a resolution of 640 x 480 (again, maximizing the vertical resolution).

When I first tried this I just selected the canned 640 x 480 export option and that was fine for the SD 700IS pictures but the result of the 30D pictures was 640 X 426, as the export wouldn't exceed the 640 resolution when maintaining the correct aspect ratio. This resulted in a "border" around the picture on the n800 since it wasn't utilizing the full vertical resolution. Using the custom setting is the way to "force" the 480 vertical rez.

Anyway, it takes Photoshop Elements about 3 minutes to export around 250 pictures from one of my typical vacation albums, which are a mix of D-SLR (30D) and point-shoot pics from the SD 700. Instead of an album being over 500 MB, its around 25 MB and the pictures display almost instantly since there's no "on the fly" scaling on the n800. Well worth the extra few minutes imo (and if you happen to be using Photoshop's Album feature anyway ).

For what its worth
