Write EXIF into JPG with PHP

Question

For a couple of days I\'m trying to write (or update) EXIF information (geotag, latitude and longitude) in a JPG image using PHP. After consulting many sites without success

Answer 1

The only way I've found is to install PEL - the PHP Exif Library

Answer 2

The gd or ImageMagick libraries will help you do this sort of thing. If you are using shared hosting one (or both of them) may have been installed for you.
