Thanks for this update and for the additional details. With regards to the four points in your latest post:
1) To map EXIF data to taxonomy terms (and other fields), open the Settings/Media Library Assistant screen and then click on the IPTC/EXIF tab. Scroll down to the Taxonomy term mapping section; you will see all of the taxonomies in the Field Title column. In the EXIF Value column, enter the EXIF field you want to take the terms from (“XPKeywords” in your case) on the row for the taxonomy you want to update. Change the Priority value from IPTC to EXIF. You can probably leave the Existing Text field set to Keep; change it to Replace if you want to delete existing terms before adding the new EXIF terms. For hierarchical taxonomies such as Categories and Att. Categories you can specify an existing term as the parent for your EXIF values. Scroll to the bottom of the screen and click Save Changes to save your work. After the screen refreshes, you can click the “Map All Attachments, Taxonomy Terms Now” button to go through the images already in your Media Library and map their EXIF data to the taxonomy terms. Any images you add after setting the rule up will be automatically mapped when the images are uploaded.
2) You can make the “latest uploaded images” process easier in a couple of ways. On the Settings/Media Library Assistant screen General tab you can scroll down to Media/Assistant Table Defaults and set the Order By value to Date, set the Order to Descending and then scroll down and click Save Changes to update your settings. The latest uploads will appear at the top of the list by default. Another approach is to pull down the Screen Options at the upper right corner of the Media/Assistant screen and check the box next to “Date”; that will display the upload date as a table column. You can click (twice) on the column header to sort the table in descending order by upload date.
3) I’m not sure what you mean by “the image listings”, but if you mean the Media/Assistant submenu table you can pull down the Screen Options and check the box next to the taxonomy you want to display as a table column. If you want to display the categories as part of an [mla_gallery]
shortcode, let me know and I will give you more information on how to do that.
4) As you’ve already discovered, there is an “Edit Media” button in the admin bar that appears for logged in users. This button takes you to the Edit Media screen where you can change taxonomy terms for the image. Displaying the categories and tags is a reasonable idea, but it is dependent on the theme you are using for your site. Modifying the “front end” (non-admin) pages of a site is beyond the scope of the MLA plugin.
I hope this give you the information you need to map EXIF data and more easily find your latest uploads. If you have any problems or further questions, let me know.
