Question

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.

Answer 1

You can save a large amount of space, especially if you have a large number of images..

Add the following to text.txt (format of the IPTC tags taken from here):

2#110#Credit='My Company' 2#05#Object Name='THE_OBJECT_NAME' 2#55#Date Created='2011-02-03 12:45' 2#80#By-line='BY-LINE?' 2#110#Credit='The CREDIT' 2#115#Source='SOURCE' 2#116#Copyright Notice='THE COPYRIGHT' 2#118#Contact='THE CONTACT' 2#120#Caption='AKA Title' 

Strip all existing exif data from the image

mogrify -strip image.jpg 

Add the credit to your image
