How to auto-fill TITLE, CAPTION, ALT and DESCRIPTION fields when I upload media

Thanks for your question and for the link to your screenshot.

You can use MLA’s IPTC/EXIF mapping rules to automatically fill the WordPress standard fields as items are added to the Media Library. You can find more information in the “IPTC & EXIF Processing Options” section of the Settings/Media Library Assistant Documentation tab.

For your particular examples you can enter a Content Template in the “EXIF/Template Value” text box. The “EXIF/Template mapping with Content Templates” section of the Documentation has details and examples. There is no specific support for your “(Incrementing number from 0 to 9999 for every new image upload)” but you could use the “post_id, ID” data source to get something similar. For example, in the text box for the Caption field you could enter something like:

template:default demo text [+ID+]

Which would put something like “default demo text 1234” in the Caption field. The examples in the Documentation should give you a good idea of what’s possible.

I hope that gets you started on composing automatic values for the standard fields of uploaded items. I am marking this topic resolved, but please update it if you have problems or further questions regarding the above suggestions. Thanks for your interest in the plugin.
