If you’re not on a photo-sharing site then go with Flickr. In fact, if you’re on Google’s Picasa and you’re not using their desktop software you might want to switch because now Flickr has integrated Picnik with robust tools for editing your photos right on the web. This is a huge advantage if you’re just sharing your photos on Facebook or the like. If you want to be able to print your photos or share full resolution images then stick with Picassa. Or just use both. 🙂
