I found the simpler way to trim the 3 pixels from the edge. Select - All, then
Select - Shrink, specifying the 3 pixels.

OK, figured that out. Had to use "Crop to selection" from Image menu instead of
Crop from Tools - Transform Tools.

Running behind on trying things but here's an update.
I zoomed in on the photos processed by the version of the script I used (the
"new"version), and there is a 3-pixel-wide strip (of varying intensity and
color, if a color image) all around the edges that causes the visible artifacts
I see.

Figured out my issues with fuzzy select and now know how to use it. Now after
lots of experimenting just with that sample greyscale photo, I conclude it does
NOT work well for my purpose. There is apparently too much variation in the
border area, so a low threshold does not get all of the border, a

On that image, the script worked extremely well, judging from the final image in

Yes, there are certainly plenty of groups of images that are the same size, so
this could work.

Just starting on this project, so I need to check on greyscale scanning of
greyscale images with color casts, versus color scanning with post-processing to
correct. So for now I'll put aside the greyscale images and just consider color
ones.
I'm scanning with a Fujitsu ScanSnap ix500. The automati

Hi - thanks for the quick reply. I wondered if it had to do with the slight
non-uniformity of the pixel color in the border. I appreciate all your advice,
but I really wanted an "automatic" process because I have a LOT of these
bordered photos, and hoped to batch process them.
I see what you mean

I have scanned photographs which have a white border. I try "Crop to content"
and get the following popup:
"Cannot crop because the image is already cropped to its content."
The border is unchanged.
I thought that possibly there are some pixels on the outer edge of the border
that are confusing
