I’ve been using Just Blog It for a while now, it’s an extension for Firefox. While it doesn’t seem to be listed on the main Firefox extension sites, there is now a version 2 – which I must have found somewhere – as it’s installed at home.
The developers site is Warmbrain – though that’s not where I got it originally! It supports more blog software than the previous version, and, better, allows you to store the details of up to 5 blog accounts – which is rather handy.
His Photo Album also is similar to the one that I’m trying to create for my personal site, from the tutorial that Craig Grannell wrote for Internet Advisor (see his Images of Iceland for an example).
