My photos start as RAW and then using the camera software I extract to jpg (which end up about 4-6 megs). Yes I use Thumbsplus at 100% during the batch resizing which actually increases the the number of megs per file (yes no compression). Using my settings in Shozam I mentioned before, the files are compressed quite a bit actually from what I see in the folders it creates. Sizes are roughly as follows: small image - 6k, med image - 90 to 150k, large - 250k.
Thanks for the info about ACDsee, I have downloaded the beta and will take a close look at it. I generally don't do any editing to any of my photos other than cropping.
I mostly use Thumbsplus for batch processing: resizing, rotating or cropping. It mostly is a catalogging program for images and that's mainly what I use it for.
Since my site and gallery are hosted at Yahoo I use their sitebuilder program to create my website just for ease of use, but I will be moving my gallery to another server soon just because of space and data transfer. Yahoo is fairly expensive to add additonal space and data transfer. It's merely an edited template I found which I liked. I am familiar with a few other programs such as frontpage but found sitebuilder to be very simple to use and causes no problems with my gallery, unlike some of the issues with frontpage extensions. I use a simple flash builder for the animations.
I hope my info is of some help to you and not just a bunch of using "dribble". I've been quite happy with Shozam since early beta. My biggest complaint so far is that during the creation of my gallery it's a bit slow. I'm going to try your suggestion of doing all my processing (compression) before putting photos in the albums and see if it's not faster.
Looking forward to seeing your gallery
