At the moment i run two different actions to resize my photos to post on my blog; one if they're landscape and one if they're portrait. They do exactly the same thing, except obviously when it's landscape i resize it so the width is 700px, and if it's portrait the height is 700px. I'm changing my actions to include a HPF instead of USM, and was wondering if there was a way to combine the actions so i only have to use one? I'm sure there's a way to resize an image to fit into a set 'box' size (without using percentages). 
Thanks!

Thanks!
