I don't like to use hide and unhide. I was thinking of adding a field called password. If someone clicks on the image field then I wanted the program to request a password.
Or to make the image field protected or Read only unless a password was entered. The password I'll give it to them verbally.
Assume they must type PASS12345. Then when they type it will change the attribute on the image field. I know the concepte but not how to write it.
