Few days ago there was some upgrade in wordpress.org plugin directory, I noticed it for first time while I was searching for a plugin. When I reach that plugin page I saw a shiny Custom Header Image in that page, I was amazed as this custom header image thing giving a whole new look to WordPress.org plugin page. I was thinking how it is possible as I didn’t know matt already told about this in wpedevel. But I check the source of the page to find the header image location and i saw images stored in assets dir of svn and the image size was 772×250. So I also give a try for my plugin and I saw it’s really looking nice. Later I googled for details about this change and I finaly found matt’s note at at wpedevel.wordpress.org. Here’s the exact quote of how matt told about this:

As an experiment we’ve turned on custom headers for the plugin directory. If you’d like to try out this feature:

1. Make a 772×250 pixel jpeg or png. (No animated GIFs. )
2. Check it in to your plugin’s SVN directory with the path assets/banner-772x250.(jpg|png). Note that the assets directory is added to your plugin’s root directory, not trunk.
3. On the next plugin directory refresh (every 15 minutes or so) you should see your image start showing up on the page.

And I additionally think if wp.org enable plugin developers to design their plugins page contents too under certain conditions and formats, It’ll be excellent.
