Phil will have to look into adding it to GitHub, but the big problem with hosting the files on exiftool.org was the fact that AI scraping bots are very abusive and hammered the website constantly. This is the reason that the forums have been offline. The web hosting company demanded an exorbitant amount of money due to the extreme amount of traffic that AI scrapers were causing.

Looking further at your script, I didn't catch that you were running two separate exiftool commands. You can combine both of these edits into a single command so you don't have to make two passes over the files. Adding in the -if option, the result would be something like this: exiftool -if "not $Orientation or $Orientation#!=1 or $ThumbnailImage" -thumbnailimage= -orientation=1 -n -m -P -r . -overwrite_original_in_place Since you seem to be running the command on Windows, I would also suggest that...

This is an informational note for anyone who runs file synchronization software and also uses ExifTool. Let's say you have a folder containing an assortment of different file types and you create another folder as a backup. Then you run exiftool commands to change the orientation of image files to horizontal and to delete any thumbnails on the first folder. You would expect the two folders to no longer be identical. However, you would not expect (or at least I did not expect) that ExifTool would...

For example, you run commands on foobar.jpg to change the orientation to horizontal and delete thumbnails, but foobar.jpg was already oriented horizontal and already had no thumbnails You are running a command that changes the Orientation and ThumbnailImage. It doesn't matter that it is changing it to the exact same thing, you are still ordering exiftool to edit the files. The file sizes change due to FAQ #13, Why is my file smaller after I use ExifTool to write information?. If you don't want to...

This is Common Mistake #5c You use an equal sign when you want to set a tag to a static value, but you use a greater/less than sign when you want to copy one tag to another. In your command, you are trying to set ModifyDate to a value of ${EXIF:ModifyDate; substr($_,0,4)="2009" not trying to copy the changed ModifyDate back onto the original tag. Try: exiftool '-EXIF:ModifyDate<${EXIF:ModifyDate; substr($_,0,4)="2009"}' ./2009_080823-053923-00_OCF.jpg

Any chance you can give me a before and after xmp sidecar? Now I'm really curious.

XMP can be embedded in a JPEG. Most programs that I know of will usually do this by default Ok, I may be wrong about this. I just updated Darktable and going through the setup, it seemed to indicate that it will be using sidecars by default no matter the file type.
