Thanks for your question. I want to make sure I understand it completely and gather a bit more information so I can give you some guidance.
The first step in this process is mapping the IPTC keywords to a WordPress Taxonomy and assigning the keywords as terms to your items. MLA provides mapping rules on the Settings/Media Library Assistant IPTC/EXIF screen; have you created the rule(s) you want?
The second step is composing the [mla_gallery]
to display the images and displaying the terms. There is an MLA example custom plugin for that, and I will find it for you. Other than the hyprlinked tags, have you worked out the [mla_gallery]
shortcode you want? If so, can you post it to give me a starting point?
The final step is creating the destination you want when a term is clicked. The most useful destination is a page containing an [mla_gallery]
that will display the items matching the term. Is that what you want? If not, what destination do you have in mind?
Thanks for any additional information you can give me.
