This page allows you to convert the handy links that you get on a flickr/picasaweb image page, into IMG tags that work on Ars' Openforum.
To use, copy & paste the flickr/picasa html link into the first textbox and press the "Process" button.
If all goes to plan, your new link will be shown in the OpenForum textbox ready for you to copy & paste directly into your forum post.
How this works:
It's a simple regex transformation that grabs the first two urls out of the 1st textbox and sticks them into a openforum [URL=x][IMG]y[/IMG][/URL] string.
This should work (famous last words) with any html of the pattern:
<a href="x"><img src="y"></a>.
