Photo app that can let you add information? Control speed of pics switching?

[marlopoohbear]

Hello. I did a search of the forums but didn't find information on this topic. Is there a photo app, or can this be done in Gallery, that would allow me to add text description to each photo? Like "My friend and his cat." Not add it to the image itself, but be available when viewing the image in the details.

Another question - when running Gallery slide show, is there a way to choose or exclude photos, and is there a way to control the speed of the slide show.

Thanks in advance for any insight.
