also if above not available…
for images added to media library we can see keywords field in IPTC section filled automatically and not possible to change – can we make this field editable by hand or by using any other plugin feature to inject data eg from any other field there?
Thanks for your question.
MLA provides several features to extract keywords and other metadata from image files and update the WordPress database with the values. I regret that MLA does not have any features for changing metadata within the image files themselves. I made an early design decision not to have any features that modify the files directly. I do not know of any other WordPress plugin that provides that capability.
I regret that the news is not more positive but I am marking this topic resolved simply because I have answered your question to the best of my ability. If you do find a solution consider posting an update here so I and others can benefit. If I did not understand the question, any additional details would be helpful. Thanks for your interest in MLA.
