how prevent users from deleting or saving files

[cfmoore]

I want to place one stand alone computer in a public area that people can use to look for and view photographs.  MS ACCESS, completely meun driven, will be the means to locate and display thumbnail with a button to display a full sized photo.  IrfanView will be the program to display the photos.  In doing so, I do not want anyone to be able to do anything else, such as save or delete.  Changing file property to read only does not prevent a deletion for happening.

There is a program called DeepFreeze that will restore the computer to a certain state everytime it's rebooted. It won't prevent them from saving/deleting, but when there is a problem you can just reboot to restore the state.

Another alternative, if you want to go with free utilities, is Microsoft's own SteadyState:

Although SteadyState is being discontinued, it should work just fine for your purposes...

You could use permissions to prevent them from deleting, assuming you're using NTFS as the filesystem.

Sid - your idea is probably the best one but I will try Killer255s idea also.  When I tried to schedule the task a system error resulted when I clicked the finish button with msg  "Unable to establish existance of account specified".  So one problem solved now I need to work on the other
