the whole code would be in the functions.php

/**
* Gravity Wiz // Multi-File Merge Tag for Post Content Templates
*
* Enhance the merge tag for multi-file upload fields by adding support for outputting markup that corresponds to the
* uploaded file. Example: image files will be wrapped in an <img> tag. Out of the box, this snippet only supports
* images and is limited to the 'jpg', 'png', and 'gif'.
*
* The default merge tag for the multi-file upload field will output the URL for each of the files.

Hi Romel

Thanks for the link.

Can you please point out which part of that allows me to enter a title for the file? This is a key requirement for me.

Thanks
Nick
