I have a MS Surface pro 1 computer with 128 GB added memory on a SDXC card. On this SDXC card I store mpst of my photos. SDXC drive letter is "H:"

I can add folders from drive H: using explorer as well as from "inside" the Gallery app but for som reason , my photos will not show in the Gallery.

I've read some coversations about this kind of matter in the communiy but nothing conclusive to fix the problem. Help appreciated. Otherwise my investment in this fairly expensive SDXC memory module will be in vain.
