Convert 52 Images to .AI

I have 52 finished mahjong-tile graphics that simply need to be turned into clean, editable Adobe Illustrator files. No restyling or touch-ups are required; I want each piece replicated exactly as supplied, just in vector format so the engraver can scale them without loss of quality...
