TypeOfMem(address)
            a1

Described in the 1.2 Exec autodocs (as in the 1.2 Native Developer Update
disk set available from CATS for $20 US [+$5 shipping outside US]).

I thought I saw a couple of those come by here just recently.
Here's what I would try, off the top of my head (ie non-tested :-)

   - set up a null RememberKey (intuition thing)

     struct Remember *greallockey = NULL; /* Graphics realloc key */
     struct Remember **grkeyaddr = &greallockey;  /* we need addr of key */

   - pass your function address,size,and grkeyaddr

     maybeAlloc(addr,size,keyaddr)
     ULONG addr, size;
     struct Remember **keyaddr;
        {
        ULONG newaddr;

        if(TypeOfMem(addr) & MEMF_CHIP)  return(addr);
        else if(newaddr=AllocRemember(keyaddr,size,MEMF_CHIP))
           {
           CopyMem(addr,newaddr,size);
           return(newaddr);
           }
        else return(0);
        }

   - In your cleanup (after you are sure you are not displaying any
     of those images anymore). 

        if(greallockey)  FreeRemember(grkeyaddr,TRUE);
