Add a UNC directory path options for photos in the Train AutoML tool

[DougBrowning]

I want to train a model that links our summary data indicators (like bare ground %) to our photos.  The Train AutoML tool takes attachments but it assumes the images are attachments in the service or GDB.  I would like a way to instead link to photos on the file system.  Most big photo datasets are pulled out of services.  We have over 600,000 images so that would not go well in a hosted service.  We do have a URL to a HTML page in the table that is a gallery of images now.  But I can also add a field that has a UNC path link to a directory full of images for each site (6-20 photos per site). 

So my wish would be that a path to a directory in the table can be used.  I could see this as an option in the tool that asks which filed points to the photo directory type thing.  (Hope that makes sense.)
