Batch Processing

Selecting-all and going PLUGINS>IMAGES>METADATA>EDIT IPTC only does the first image selected - not the whole directory

You can install Digikam to batch edit the iptc data for all images at the same time.

Yes tried Digikam but it seems to have the same problem.
There is no IPTC listed in the batch processes.

Well, try to install the kipi plugins

if gwenview, or Digikam not supports Kipi plugins
you can try with http://www.jalix.org/projects/showimg/ that supports it very well

http://www.kipi-plugins.org/drupal/

Hope This Helps

Thanks ivancete but I do have the kipi plugins installed.
They are installed and activated.
As I said in the first post - I CAN edit IPTC data on individual images (not possible without the plugins) but I cannot do it as a batch process

In Gwenview - under the Plugins menu I have:
Batch Processing:
Border images
Color images
Convert images
Image effects
Filter images
Rename images
Recompress images
Resize images
RAW images converter

In DigiKam - under the Tools>Batch Processes menu I have:
Batch Processing:
Border images
Color images
Convert images
Image effects
Filter images
Rename images
Recompress images
Resize images
RAW images converter

There is no IPTC in either of the Batch Process lists.

Well, you can search for an applicattion that can do batch process for iptc, i dont know if its possible, you should search it in: http://www.getdeb.net/browse.php

Good luck

Thanks Ivancete - I found I can run Irfanview via crossover ( wine ) and that will do batch IPTC data .
maybe Gwenview will get this feature in future versions.
thanks
