1 GByte (1024 MByte). Tools... Database Utilities... Compact is vital;
if you're getting close to a gig, corruption becomes more of a risk.

storing them as external files (and storing the path and filename in a
Text field) instead; or store them as BLOBs rather than images. Access
is HORRIBLY inefficient at storing graphics.
