Sometimes I like a bunch of photos streaming by every few seconds, but at other times I want a single photo to be displayed for a few minutes, an hour at a time, or all day.

Would it be possible to add a configuration option that lets you set the pause time between photos?

I'm thinking of a simple drop-down menu named "Display each photo for:" that has the following entries:
5 Seconds
10 Seconds
15 Seconds
30 Seconds
1 minute
5 minutes
10 minutes
1 hour
Forever

The "Forever" option would turn off auto advancing through photos. This would be a very useful feature on those days when I just want to see that cute picture of the kids that I took last week when we went to the beach. Then, if I change my mind I can simply flick through until I find a different photo that I like and then just have that one displayed (until I change my mind again).

Thanks!
