Costco crops: action to add 1/8" border?

i am using lightroom 2.4. I know i can export to photoshop to run this, but is there an easier way to do this? what i want to do is when i export my photos out of lightroom to run an action which adds a 1/8" border to the canvas so it will crop that and not touch the photo?

Sort of like printing a 4x6 but making the 4x6 a 4 1/8 x 6 1/8 so when costco crops the picture it crops the "extra space off"

do i have to export all 200 plus pics from raw to jpg then run it through photoshop to run the action to add space, or can i some how do this in lightroom?

Download the Mogrify plugin. This will give you a heap of options for adding borders/text/logos etc. It's a little fiddly to get setup but once done it is quite easy to use.

Ill second Mogrify. It works great. But you have to donate or it gets limited to a 10 image batch. But he will take anything as a donation and give a key.

I bought it for 2.00
Works great
