Let the Sunshine In: Software support engineer in Tokyo

I use firefox2 and I often see blogs.sun.com entries where graphics(such as screenshots) are unreadable because it's squeezed according to style sheets. Examples are:

Trying out search , search referral feature in LDAP BC : Sainath Adiraju's Blog Zone
Java CAPS Tip : Application Reconfiguration : The Crooked Stick

Look at graphics at the bottom of these 2. There are some workarounds.

1. Firebug to tweak stylesheet on the fly.
   
2. My greasemonkey script will un-squeeze those images to 100% in most cases. But this script only works for about 15% of all blogs.sun.com blogs.
   

What's the best style sheet setting to avoid this to begin with? My guess is there's no answer that works universally.
