Thank you for your post, and I apologize for the late reply.
You mentioned you would try to recreate the layouts in FileMaker Pro 12. Have you found any improvement in performance? Are you viewing the records in Form View? List View? Table View? How many graphics are being displayed at one time? Are the graphics all coming from the related table?
Is it possible you could send in a copy of your file so we can test it here to find out what is causing the slow performance? If so, check your Inbox at the top of this page for instructions where to send the file.
