LumemLux Infranview won't allow drag & drop - get ACDSee 5.0 from ACDsystems.com - this program will allow batch resize, rotate, rename plus drag & drop arrangement of thumbnails. After you arrange them in the order you want you will need to rename them with a sequential number so they show up in p2e that way. ACDSee most definately the fastest viewer and DAM out there. Good Luck - Shooter
