The other day I got a message today from killes that the Drupal Planet was getting a ton of 404 errors on the images in my posts because I was using relative URLs, and because I've been going a bit gangbusters on the imagery lately, the errors have been compounded. These 404 errors pollute the error logs, making is more difficult to identify important errors, and apparently I'm not the only one with this issue. You, too, could be responsible for log pollution!
Luckily, I ran into a module called Relative Path to Absolute URLs a while back when figuring out how to send launch MailChimp campaigns from Drupal (module forthcoming) that will add an input filter to convert relative URLs in your images and links to absolute ones. So, I installed it, enabled the filter, and all was well with the Planet.
If you're contributing to log file wash-out with relative paths, use Relative Path to Absolute URLs and help keep the Planet clean.
