I'm not entirely sure what you mean by "photo album" in the context of Spine. However, if you're referring to the Images node in the Spine tree, here's what I can share:
The images node automatically stays in sync with the file system. Images on your skeleton will update immediately if changed externally. Filesystem manipulation is best done using the actual filesystem rather than within Spine itself.
If you're asking about texture packing, Spine gives you control over how images are organized and packed through its folder structure system. Images in the same folder go on the same set of pages, and you can use subfolders to group related images together. You can learn more about this here: https://esotericsoftware.com/spine-texture-packer
Could you clarify a bit more what you mean by "photo album" and "facility for material control"? That way I can give you a more precise answer!
