We want to keep a photo file on her web site based on Joomla But we want to lock it. once someone want to open a file the person has to fill up the personal information and send it to Tina, Then after viewing the person profile we would send a generating code number to open a file, and also put limit not able to copy that her pictures on the file. Do you have any idea or program like that?
That must be a pretty special photo to go to those lengths however once you eventually give people access you relinquish control and it can be copied and distributed any number of times.
If it's available to view, it's available to be copied/downloaded and more. Nothing you can do about that.
