Converts images from one format to another while keeping any metadata.
Usage: convert-keep-metadata.sh [TARGET_EXTENSION] [FILES..]
Converts images from one format to another while keeping any metadata.
Given [FILES] are converted the format specified by [TARGET_EXTENSION]
After converting the image, metadata from the original is applied to
the target image. The destination image metadata may contain
duplicates, but metadata is not likely lost in the conversion.
Tranferring the original metadata in an exact form is probably a
non-trivial task..
[TARGET_EXTENSION]
See "convert -list format" for valid extensions.
[FILES..]
Path(s) to the images to convert.
convert-keep-metadata.sh is free. You can redistribute it and/or
modify it under the terms of the Do What The Fuck You Want To Public

Finds corrupt images by using external tools exiftool and jpeginfo.
Detects corrupt images from reading contents and metadata. Good for sifting through data produced by data recovery or forensics. Does rudimentary argument checking, but there are bound to be bugs. Reads file type from the "magic" header bytes, so file extension should not matter.
-
Looping over results
Generic usage template. Note that you should probably research handling "weird" file names properly, like those containing spaces, etc.
~/Bin/detect-bad-images.sh -b ~/Pictures/* | while IFS='\n' read -r f do [ -f "$f" ] || continue printf "do whatever with %s ..\n" "$f" done
-
Remove bad images
Deletes images deemed "bad". There is no undoing deletion so be careful!
find ~/Pictures -type f -exec ~/Bin/detect-bad-images.sh -d '{}' \;
To display usage information, run:
~/Bin/detect-bad-images.sh -hProbably won't be complete though.
Auto-adjusts images based on metadata, file size and image dimensions.
Originally written for automatically modifying images uploaded to the 'Camera Uploads' Dropbox folder. For instance, all images shot by a certain camera/device might need to be resized or have the white balance auto-adjusted if the image size is above a set threshold.
To display usage information, run:
~/Bin/auto-adjust-photos.sh -hProbably not complete.
Preview videos and interactively rename them to indicate what should be done by other tools.
Renames images created by the "Full Page Screen Capture" Chrome plugin.
