I’ve been using RoundCube Webmail for the last month or so, and it’s pretty slick for an early release. One feature really bugs me though: it defaults to blocking all images in messages until you click to load them, and doesn’t provide an option to toggle this behavior.
If you have good spam protection on your account already, you can automatically load images by finding the following block of code in program/steps/mail/show.inc and changing it to read:
// check if safe flag is set
$MESSAGE['issafe'] = 1; // override to always display images
// if ($MESSAGE['issafe'] = intval($GET['safe']))
// $SESSION['safemessages'][$MESSAGE['UID']] = true;
// else if ($SESSION['safemessages'][$MESSAGE['UID']])
// $MESSAGE['is_safe'] = 1;
