It's a good idea. I haven't been using Picasa for photo storage, only as a platform to share blog photos. I've only been uploading 600 pixel versions of my pics since that's all I need for AP. My full res photos are stored offline on three different backup drives in different locations. Given Picasa's retirement, it may be a good time to reconsider the merits of online storage of all my full res photos.
@Revy, yes, Flickr and SmugMug have the embed feature. One thing I like about SmugMug is that it's designed for photographers, and there isn't a free version with some "catch" to it. They're not trying to sell advertising or get you to accept it as part of Yahoo's services or whatever. It is used by pro photographers who sell their photos as digital files or prints, T-shirts, etc. On the flip side, I guess I'd be paying for some features I don't need.
Recent reviews of Flickr have been less glowing but it's still an option.
I see that "Attackpoint" Ken uses SmugMug to share his orienteering photos. I think Wil Smith uses it too so there are a couple of knowledgeable people who could offer opinions. Hmm. Thanks for wrecking Valentine's Day, JayXC. ;)
