Polling the Audience: Photos on this Blog

After moving to a private server, Dreamhost has informed me that I’m using more resources than before (what?), and as such my hosting bills have increased. The biggest culprit seems to be WordPress’ built-in Gallery feature, along with the Lightbox-style image displays I’ve been using to share larger copies of my photos.
I’ve been experimenting with using a combination of WP Gallery, the NextGen Gallery plug-in, and hosting photos on Flickr to see which would be the least drain on my server’s resources, and Flickr is the winner, hands down. The problem is that if I use Flickr to embed images in my posts, you can’t see the full-size versions unless (1), you click through to Flickr and (2), if you’re one of my Flickr contacts.
So I’m asking your opinion: do you like it when I use lightbox to display my photos on this site? Is the Flickr embed good enough? Do you care whether I post my photos here?
Please leave your answer in the comments. Thanks!
