20080823 0607 GMT-6 Yesterday many teachers uploaded new pictures. Right now all the original picts are 600 and all the thumbs are 644. I know for sure one teacher deleted a file and it did not remove the original files. As a note - I did find this yesterday. One of the teachers only uploaded one picture. That one picture was permission 664. Im not sure why though. Their original server was windows but have since moved to some version of red hat. I think (if I push hard enough) they will be moving to a ubuntu server soon. I dont think RH has any extra feature like you were saying. Wade
