General is very problematic - not because it handles only pictures, but because it is very hard to get things out of it. Also because the size of the DBT (memo) file will increase much faster than the contents stored.

Even if you use a BLOB field, you might quickly reach the Visual FoxPro limit of 2 GB per file, so storing only the filenames is the only sensible thing to do.
