Use this script to generate a new file with the same document heigh, width and resolution.
if (app && app.documents.length > 0) {
var currentDocument = app.activeDocument;
currentDocument.activeLayer.copy();
var newDocument = app.documents.add(
currentDocument.width,
currentDocument.height,
currentDocument.resolution,
currentDocument.name + "Copy" ,
NewDocumentMode.RGB,
DocumentFill.TRANSPARENT
);
newDocument.paste();
}Then record the following steps:
1 - Run this script
2 - A crop, but remember to mark the second box.
you still have to cropt automatically the photos, but it will have the actual document properties in all copies
if you dont know how to record actions:

@r28071715i111, are you ready to manually mark up all your photos using guides?
In this case, we can write a script that will retrieve each image based on this markup. After that, you scipt run the crop and straighten filter, which will try to align each image separately (this is unlikely to guarantee 100% success, but I think 80% of the work will be done automatically)

* code updated.
I have updated the code in the post above, try it.
MAXIMUM_RADIUS specifies the radius with which the Filters -> Other -> Maximum filter is applied. The goal I'm aiming for is to clear the image of garbage and frames.
Source frame:
frame after Maximum filter with radius 22
Next, on this cleaned image, the script executes the command Select -> Select Subject:
Then the script tries to align the image, for this it increases the selection box by the number of GLOBAL_OFFSET pixels in each direction. After that, the image is transformed by the Crop and Straighten filter:
Then I re-execute the Select -> Select Subject command and increase the selection by HEAD_OFFSET pixels up to provide free space above the head and finally crop the image within these boundaries:
That is, you can change these three constants yourself to achieve optimal results (however, it is difficult to guarantee that in 100% of cases the script will perform its task correctly).
