I'm on a Rezound running Sense 3.5. My last phone was a Motorola Droid 2, where the Gallery app was the stock Android version. In that app, you could long-press on an individual thumbnail and it would reveal 'checkboxes' on each of the thumbnails so you could select which photos to share. Then I'd click Share and send those photos to Picasa, Facebook, or wherever.
My question is: is it possible to do this in the Gallery app that comes stock with Sense 3.5 on the Rezound? Or should I be using some other app? I'd just like to avoid having to upload each of my photos individually to Picasa, since I just got back from a vacation and took a whole bunch of pictures.
