[Suggestions for the next version]

I would love to see the Time limit usage to where you cannot turn back the clock on your computer and run the slide show program. When it expires, let it be expired competly.

[The next most important features]

I would to see an expiration date that would not allow a user to change the date back on there computer to gain access to the exe file.

this would really secure the program if I am deleviring a sample file.
