Hwo to crop image in photoshop for different sizes automatically?
 

Example image 250x200 to sizes 100x100.jpg, 175x125.jpg, 110x140.jpg and so on?

record an action for each size you want to make, then run each batch process on the original image

yeah.. record an action for resizing but you'll still do it manually since those following size are not on same aspect ratio...

Yep. For good thumbs, you got to do them manually. Actions are good for some things, but unless you are cropping to the exact same ratio, it's going to crop good shit out and leave bad shit in.
