I'm looking into uploading my family's photos online using Picasa and want a good photo viewer for ipad. Based on user reviews and descriptions it looks like I've got my app purchase narrowed down to iPicasso or Web Albums. The ability to add captions using the ipad will be a plus if either one has that feature. Can you guys make a recommendation either way? For once I'd like to just purchase an app one time instead of buying multiple similar apps in search of the "best one".
