Simply do the same thing as for roms. Get the snaps (or flyers or whatever datfile), setup rompaths (in this case they point to sets of picture files) and scan. Or use the rebuilder in the usual way.

Always keep in mind the standard scan modes:

rompath\setname\rom 1 ... rom n (for unzipped sets)
rompath\setname.zip for zipped sets.

So if you look at the snapshots datfile you'll see that it only got one set called "snap" which contains all pngs.
So if you keep the snapshots zipped in e.g. D:\mame\snapshots\snap.zip the rompath is d:\mame\snapshots

If you keep them unzipped, you have to put them in a folder called "snap". So for unzipped files in d:\mame\snapshots\snap\005.png etc the rompath is again d:\mame\snapshots


If you want to limit your scan/rebuild to the sets you have, you can use settings->sets to enable/disable sets you like.


Well...that's the general way. Your request is a bit different because it sounds like YOU want to make screenshots and want to match them directly to romsets. A datfile is usually for some pre-made snapshots collections and not directly related to romsets (of course the romsetnames match the png filenames though).

Maybe you should look at Logiqx's tool ImgChk, too.
