Our Moving Pictures< exhibits require that your browser display things in "frames", and yours is reporting that it cannot do this.
All browsers can support this, so perhaps you have disabled this feature in yours? If so, you might go into your browser program's "options" or "preferences" area, and find where it will allow you to toggle on the ability to display web pages which use Frames.
Otherwise, you might upgrade your browser to a newer version, or better browser.
I recommend "Firefox" highly, but any of them should do, and your current browser's manufacturer should have a simple routine for upgrading yours to a newer version, which would support Frames.
Good luck!
