Dan,
I'd steer you away from using a general field. Just use files on disk and store the path to the file. This lets the user work with the images much easier.
>Thanks for the reply. No, I don't need OCR software. They don't want to scan in the text from a supporting document, they want to scan in the supporting documents themselves and tie them to the document they are keying in via a link table with the document image(s) scanned in, or by saving the actual image(s) into a general field. I need to be able to scan the supporting document image(s) from the data entry form by having a scan button. I don't need to have the image data converted to text via OCR or anything else.
