Help in making resizing/scaling

I have a table with 100x100 pixels per cell and was wondering if anyone knows how to resize/scale an image by giving a maximum width/height parameter? I havent been able to find anything like that in photoshop. Example: if i had a a 600x1000 portrait photo, i want it to resize to 60x100, and if i had a 1000x600 landscape photo, i want it to resize to 100x60. thanks in advance.

I cant use "percentage" since i plan on using this as part of a batch action wherein the input images may have varying image sizes and using "percentage" may result in different sized "thumbnails".

I've already considered using the file->Automate->Web Gallery to generate those files but I'd prefer it as something that I can include in one of my Actions.

Thanks in advance

Well, you pretty much "shot down" everything I could have added here.

I just don't know of any ways to do what you are trying to get on the fly. "Percentage" is the way I would go, and if they happen to be a little different in size I'd just go back and target size crop them.

some of the other guys might have something to add here.

Hi Torn, right now, ive been relegated to separating my landscape my portrait photos if i wanted to use my actions, otherwise, i make it a 2 phase process by doing the file->automate->web gallery feature and then using the images/thumbnails folder and dropping everything else.

thanks anyway,
Tanos

P.S. I have long been a Photoshop believer but this is one thing that Fireworks has over Photoshop :(
