Prepend keywords or auto-insert custom taxonomy

Hi Jordy,

First of all, GREAT plugin, loving the Pro version and the options it offers.

I’m looking to further customize the automation of the file renaming, I couldn’t find anything similar in the FAQ section.

The way the site works is the following:
1. Users register to become Members and submit posts with image(s) attachments (stored in the native WP Uploads folder).
2. Posts are pending review and activated manually by the Admin
3. Admin validates the post submission and renames the media files if need be, this is where the MFR plugin comes in handy
4. Admin activates the post after manual intervention and validation

What I am trying to do is:

Option 1
Auto rename uploaded files based on custom meta

I’m looking for a function that can automatically rename the uploaded files based on custom terms, example:
Domain name – Author – custom post category – custom post title – date

End result: domain_name-author-custom_post_category-post_title-date.jpg

or

Option 2
Auto prepend word(s) into the beginning of the uploaded image file names

Something as simple as automatically adding 1 or 2 words at the beginning of the uploaded files through a custom filter in the theme’s functions.php file to obtain the following output:

word1-word2-original-filename.jpg
