Im using BLOB fields for clients' photos and I am unable to change a photo once one is uploaded for a certain client. I can delete the photo, using xataface 'X' (but its kinda "still there"), or manually delete it in phpmyadmin. But then once I add a new photo or edit the photo, with another. I get the original file uploaded (the first image every uploaded for that row). This kinda means u cannot get a client photo wrong.
In Phpmyadmin it says "Binary - do not edit (136.2 KiB) "
