Hi,
Due to the poor design of the referencing in FPT's, storing this amount of data will cause problems at some stage. Store the images in a separate folder & have a link to it, it is slower, but doesn,t break.

I am well below the record limit for the parent table PHOTO.DBF but the size of the fpt is starting to concern me. Also… last night the FPT became corrupted. Any file can become corrupted but I am wondering if I am sitting on a time bomb.
