Other web devs notice Safari 4 diverges from old text-resize?

Now the Cmd-+/1 (or Cntl-+/-) changes size of images as well as text.

This presents web design with a new phenomenon: Whereas I used to be able to count on visitors to change font size to suit their readability needs, now I find that if/when they do the page layout may be changed my image size changes.

This might have been okay if all/most/any browsers had always operated this way. But now... what a PITA to have to rework old stategies on many sites where I've been able to count on image sizes remaining set.

Anyone else struggling with this? ...or even heard Apple announce a strategy change.
