In my current client app I am using the Display as Picture to display a roster of a list of people including their photo.  As I am starting to see a need for moving to a PowerServer endpoint I am wondering if there is a good way to display these types of photos.  Similar example would be a tree view of each class at a school grouped by teacher.  Expand the group and all the students show up.  Currently the database holds the beginning of the network folder path and using the person's id to create the rest in a computed column.

When the app is used outside of the network, resources those images aren't accessible.  Datawindows can't show web URLs, and copying the hundreds to thousands of images locally isn't conducive either.  Can you map a drive letter to an FTP folder or something?  Would saving the images as a blob and converting the hundreds per retrieve be viable?  How would this be accomplished if hosting the app and database in Azure even as a client/server approach?
