Good question.

I remember that I thought the patch should be revised (meaning I wanted
to do that if I find the time), that's why I did file it in BT but
didn't send it to the "holy list" yet ;)

Since Mario is in need for this snippet, he might want to take care a
bit and have a look at it...

I must admit I never used ex before. Thanks for the hint.

That would be a good thing, agreed.

Exactly. Have a look at www.barmer.de (has been awarded with german
BIENE award for accessibility and I'm impressed by the idea - try to
"simulate" a very small resolution like 800px in width in total and
watch the images scale down automatically) - they do it that way (if
this was TYPO3, it would require a very decent configuration, though...)

This as well is an idea (maybe more a wild guess) which came to mind
after watching the above mentioned site and peeking at the CSS.


Thank you very much for your input!
