Comment (by rsiddons):

 Folders default to 4 thumbnails but you can assign a single image to
 reduce clutter. Removing them altogether requires theme modification. But
 the Mythbuntu 28.21 doesn't show folder names so it would be difficult to
 distinguish the folders with nothing.

 .mythtv/tmp is created at startup (Temp storage group). Did you delete it
 whilst the frontend was running ? Maybe it should handle that better.

 I tested master/Mythbuntu 28.21 today and found no problem. However I can
 understand why the initial scan appears underwhelming. It's mentioned in
 "Image Gallery" para 3 at https://www.mythtv.org/wiki/Gallery.

 In brief, !MythGallery only works on a single frontend that has direct
 access to the photos (local/NFS). There's a long-term goal of moving all
 media to the backend (Storage Groups) for use by all
 frontends/webfrontend/API clients. As in !Video/Music.

 Passing large numbers of images around (for bigger TVs) is intensive so
 the backend creates a thumbnail cache (the "resource hog"). Until this is
 complete the frontend uses thumbnails that are created on-demand, so they
 appear slowly. It also competes with the backend generator so they can
 appear sporadically (thread contention).
 You can observe this with '-v file' logging of the backend.

 There have been anecdotal reports of images never appearing. If you can
 capture a '-v file' backend log and a '-v gui,file' frontend log of that
 ocurring, please post them.

 Scanning my 7.5k photos/600 videos takes 2 mins but then a further 30 mins
 to create the thumbnail cache. During this time Gallery performance is
 sluggish.
 It can be mitigated  by zooming in to display fewer thumbnails.

 However, after the initial setup, subsequent scans are fast. And Gallery
 runs off the backend thumbnails (faster than !MythGallery) and the
 frontend's image cache (instantaneous).
