ok, may be not in 30 minutes but....
here's a great tool you can use to update your blogs:
Gallery Scraper
what does it do? well, using your sponsors' FHGs it turns:
URL|short description|long description
into a blog post
here're a few examples (all the posts you see on the first page):
www.lesbopalace.info
of course you can add more text to your posts, change the thumbnail size, use as many thumbs as you see fit and so on. Gallery Scraper basically creates your own RSS feeds (using the sponsors' FHGs) with your link codes and it is the easiest way to add blog posts to as many blogs as you want (the blogs can be hosted on different hosts).
I use it in combination with blog organizer but it'll work with any blogware that works with RSS feeds.
ok, end of story
