Create an album of thumbnail size photos from Apple Photoslibrary

[StarGeek]

I'm not sure what to suggest.  That command works properly.  If it isn't finding anything, then there probably isn't any files of that size.

The small jpg you tested was in the directory

/Volumes/Photos by Year/photos-by-year/Small/

yet you are running the command on this directory

/Volumes/Photos by Year/photos-by-year/PastYears.photoslibrary/originals/

are you sure there are small images in the "originals" directory?  ExifTool is saying that there aren't.

This is the second image in the /originals/0 file, its only 75x75, or am I reading it wrong?

% exiftool /Volumes/Photos\ by\ Year/photos-by-year/PastYears.photoslibrary/originals/0/023820A9-7D52-4D40-AB0F-322BFBFE6205.jpeg

So what happens when you run this command?:

exiftool -if '$ImageWidth<=240 and  $ImageHeight<=180' '-directory=/Volumes/Photos by Year/photos-by-year/Small2' -r '/Volumes/Photos by Year/photos-by-year/PastYears.photoslibrary/originals/0/023820A9-7D52-4D40-AB0F-322BFBFE6205.jpeg'

% exiftool -if '$ImageWidth<=240 and  $ImageHeight<=180' '-directory=/Volumes/Photos by Year/photos-by-year/Small2' -r '/Volumes/Photos by Year/photos-by-year/PastYears.photoslibrary/originals/0/023820A9-7D52-4D40-AB0F-322BFBFE6205.jpeg'

    1 image files updated

Now I'm even more confused.

[kkaiser]

I'm running (yes running):

exiftool -if '$ImageWidth<=240 and  $ImageHeight<=180' '-directory=/Volumes/Photos by Year/photos-by-year/Small2' -r '/Volumes/Photos by Year/photos-by-year/PastYears.photoslibrary/originals'

And its working. In just a few minutes it has identified and moved 1140 small photos to the Small2 file.

It looks like the only difference is the / at the end of originals. Is that true?

[kkaiser]

It finished;

% exiftool -if '$ImageWidth<=240 and  $ImageHeight<=180' '-directory=/Volumes/Photos by Year/photos-by-year/Small2' -r '/Volumes/Photos by Year/photos-by-year/PastYears.photoslibrary/originals'                                           

   17 directories scanned
101251 files failed condition

The slash at the end won't matter.

Ah... The problem was that you had a funny Unicode non-breaking space in your -if condition:

'$ImageWidth<=240 and  $ImageHeight<=180'

Immediately after the "and" is the funny character.  You can get this by copying and pasting from your web browser.

If I copy and paste your bad command and add the -v option, I see this warning:

Code Select Expand

Condition: Unrecognized character \xC2; marked by <-- HERE after }<=240 and<-- HERE near column 29

That was probably my fault.  I usually make sure I don't have double spaces when I list a command here because the forum does that.  I didn't do that in the example I gave.  Fixed.

Poop happens! All is well.
