Be also aware, that if your PICT resources  (if that is the source) are 
not marked as Purgeable using ResEdit or other, then you will need to 
dispose of the handles associated with them, after unlocking them.

If they were created with OpenCPicture, or Picture On/Off, then use 
Kill Picture Picthandle.

If they are marked to be purged, then you can just unlock the handle, 
and don't worry about it afterward. The Memory Manager cleans up when 
needed (in 9.x.x and below, not sure about X in that Dept. :)

Others may need to fine-tune this aside...my brain is foggy right now.
