I'm not happy with Silverblog, either. As I mentioned in the edit to my original post, I want to be able to link to photos already uploaded to my Flickr photostream rather than upload photos directly to my photoblog. It will be quicker, easier, and require much less storage space than direct uploads. Unfortunately, Silverblog doesn't seem to offer that option. Besides, I'm having trouble getting Silverblog to work properly.

I haven't had time to look at this since i made my post. However, I now feel the best option may be to use Wordpress or other "regular" blogging software and simply customize it to get a one-post-per-day photoblog. As Cal mentions, there's not not only a dearth of good photoblogging software, there's also the problem of getting those available to work, or at least to work the way you want.

Anyways, I appreciate the comments and will still welcome any new thoughts or ideas anyone migh have. Thanks!
