Originally created Fri, 23 Dec 2011 - 10:50. Moved here to separate from other image topics.
Also watermarks require some doing.
- http://drupal.org/project/watermark D5 only - http://drupal.org/node/214454 imagecache patch, tutorial for D5. D6 ??? not clear - http://drupal.org/project/imagecache_effects D6, some issues, maintenance status unknown - http://drupal.org/project/imagecache_actions D5, D6 - widely used, no online documentation?; addon to: - http://drupal.org/project/imagecache D5, D6. D7 integrated in core - http://koukounari.gr/watermark-images-in-drupal tutorial, 2009 (looks good)
IMCE supports watermarking Obviously this only works when using IMCE for image insertions - http://drupal.org/project/imce_watermark D6 and D7-dev not overly used addon to - http://drupal.org/project/imce D6, D7, widely used
IMCE uses watermarking via script or by using submodule imagecache_canvasactions of above addon module imagecache_actions.
Well. Time for some lengthy experimentation.
Trying: - http://drupal.org/project/imagecache_actions D5, D6 6.x-1.8 there are some warnings in the readme.txt file, amongst others, about caching
Not working properly. Enabled Canvas Actions. Following various instructions, I created a transparent small watermark.png file with a short text in it and uploaded to the sites/default/files directory. The text appears on the image, but it is in bad quality and has a solid black background. Well. Back to the drawing board.
Workaround: Disabled and uninstalled Canvas Actions, enabled Text Actions. Here we can overlay a text, i.e. a copyright text. That is working OK. Using this in the meantime.
