I've been playing with thisMoment, which is in public beta. (ReadWriteWeb reviewed it back in January.) The service allows you to gather photos and videos from your computer, Flickr, and/or YouTube and tie them together in a "moment" - a scrolling slide show that you can pin to a particular place on the map and link to Wikipedia entries and other sites. You can also tag others in the moment with you.
When you view an individual moment on the site, you have the ability to scroll through introductory text and then arrow through the associated photos and video. A small magnifying glass button expands the current photo into a new frame for a larger view.
The interface is pretty simple, and it's neat to be able to tie everything together within a timeline. There isn't a way to upload current photos from your phone, but loading them into your Flickr account would enable you to bring them over into a "moment." I would like to have the ability to tag individual photos within each moment, and unless I'm missing something, that isn't an option right now.
Here's one of my moments (see robinrkc.thismoment.com for the full moment):
