I use Samsung Evo cards and have never had a problem with images and the sizes.
As for shrinking the image… there are programs that will do it.
Personally I would use DiskInternals linux reader… mount the image.. and then export the files to your desktop into a folder and then go into those filess… take out what you dont want for roms.  Then, recreate the image using all the remaining files in your new desktop folder.
