On our site, we get a large amount of photos uploaded from various sources.
In order to keep the file sizes down, we strip all exif data from the source using mogrify:
mogrify -strip image.jpg
What we'd like to be able to do is to insert some basic exif data (Copyright Initrode, etc) back onto this new "clean" image, but I can't seem to find anything in the docs that would achieve this.
Has anybody any experience of doing this?
If it can't be done through imagemagick, a PHP-based solution would be the next best thing!
Thanks.
You can save a large amount of space, especially if you have a large number of images..
