ThumbPlus batchfile is great for that.

Say you have a mix of pics of various proportions.

You can resize them by percentage.

You can also resize them within a box.

So, you specify 800x800 w. keep proportion.

That will generate an image of 800 x 800 with side or top borders, depending on original proportions.

If you select the autocrop option, it will remove those borders and you'll end up with a pic of 800px long-side, no matter the proportion.

That's cool.

What I do to extract the utmost in quality/compression ratio is the following:

When I resize with ThumbPlus, I have the resized pics saved in PNG format (lossless).

Then, I run a automated action in Photoshop to convert them to jpg, because it saves with a higher quality/compression than in thumbplus.

I'm using ThumbPlus v. 4.5 R2 build 2041 from June 12 2001. Not exactly the latest version, but it works very well. I also use it for color correction. It is much faster, lighter, easy to handle program than Photoshop 6.
