I have a folder full of .jpg files of all kinds of random dimensions and sizes.  I have used php for manipulating images but it has been a while.

I wish to print them all to 8"x12" paper and have nothing cropped or stretched from the original.

What I am currently doing is manually adding black bars to meet the correct dimensions.

Since I'm printing to 8"x12" the ratio is 1/1.5 or 0.667

So a photo coming in at 3000x4000 will finalize at 3000x4500 with black on top & bottom of 3000x250

A picture coming in at 2500x10000 will finalize at 6666x10000 with black bars on right & left of 2083x10000

Hopefully I'm being clear.  The incoming photo will be of varying sizes, both landscape & portrait.  They will all print to 8"x12" or 12"x8" with no stretching or cropping.
