andrea_r has posted into the WPMU forums in this thread a link to a working tool for including Flickr images in blog posts. Its a slightly modified version of the original from TanTan Noodles.

It installs easily and works pretty much straight out of the box. I did, however, come across a niggling little problem; on my write post page I was getting the following error message:

Warning: Missing argument 1 for http_request() in /usr/local/lib/php/HTTP/Request.php on line 209

Luckily I was able to track down the problem and it was an easy thing to fix. Luckily šŸ˜‰

The fix is as follows:

edit file: lib.phpFlickr.php, line 74

orig: require_once “HTTP/Request.php”;
new: require_once “PEAR/HTTP/Request.php”;

Simple as that.
