Dear Deborah: The system you refer to is called "Tethering" and as you state, it is a helf measure. I use it sometimes, but don't like it. We have display areas in the Student Union where rotating exhibits are hung. I always screw the pictures to the wall with four square drive screws (available from McFeely's 1-800-443-7937 1620 Wythe Rd. / Lynchburg, VA 24505-1169 ; also from Brookstone & others). If the pictures are in standard metal section frames, rather than attach wire I put four wire hangers on facing out, ============================================================ Stephen B.
