I'm a month late to this thread but for storing picture I've have good luck using a binary memo field instead of either a general field or storing the name of a separate image file. Doing so reduces file bloat (caused by the general field containing not only the image but also a preview picture), and in my mind it's no more logical to keep each picture in an entirely separate file than it would be for any other column of data. How-to details were published in the Advisor Answer's column of July '99's Foxpro Advisor - basically you use APPEND MEMO [fieldname] from [filename] OVERWRITE to get the picture into the binary memo field and COPY Memo [tablename.fieldname] TO [filename] to get it back out.
