That's curious-- in my browser, the picture gets cropped, but the text remains visible. What browser and OS are you using?
EDIT: Thanks for the 1280px info.
Chrome 12.0.742.124. Arch Linux. Screen cap: http://i.imgur.com/4vEl3.png
Ah, you meant the text on the sub-pages-- I thought you meant the links on the front page.
EDIT: OK, fixed, I think.
EDIT: The problem is your 1280px width declaration in style.css's rascalcontent class. Guessing this will screw up smart phones too.
