Support for .HEIC files, or MOV files as images

I have a relatively simple app to collect client data and ask them to upload images. On my end, we are viewing these submissions in a dashboard

It has been discovered that about one in 10 clients are uploading the requested images/photos as .HEIC files and .MOV files.

When viewing my dashboard with this column as “file”, the MOV files allow me to download the file and preview it. This is acceptable, yet undesirable as now all the proper photos and image files won’t preview

The HEIC files seem to be completely inaccessible

As there is no “universal” column type for all media files, how would you suggest working around this?

I could probably specify in the form one place for photos and one place for videos… But what to do about these HEIC files?

Thanks in advance for any insight!
