You can load a sequentially numbered set of images as image clip into Resolume.

I'd use this approach to convert the image sequence into a single DXV clip, you can set the frame rate then.
Then use transform or other effects to move it in the "3d space".
If you're thinking of doing an auto slideshow with new files added automatically, that can't be done in Resolume natively currently, but if you find a program which can do the slideshow, you can get it's texture into Resolume via NDI scan converter.
