>General fields have three major problems: 1) They take up much, much, much more space than the JPG file. 2) Because of problem #1, you can easily go beyond the limit of 2 GB for VFP-files. 3) It is very difficult to get the images back out of the General field.

Entirely correct. Until VFP9, where now we can use BLOB type fields to store binaries. So now we CAN store images in DBFs if we want. Or we can keep doing it the previous way, e.g. storing only the path+filename reference, which is good advice.
