Subject:  Re: [thelist] Automatically Size User-Loaded Images

  I see us basically using this as a way to limit the image size
  so that it doesn't create horizontal scroll-bars, etc.

mmmm XHTML.

This is OK, as long as you're sure of a given aspect ratio. If the
supplied image happens to be 500 x 500, you're in trouble.

I'd thought that too, but I've been pleasantly surprised certainly by ie5+
Mac & PC. Take a look at my photo album (I know, another shameless
plug. Colour me a proud dad):
Those last few pics are all resized, none by nice round numbers (like
50%), and they're nothing like as bad as I'd expected.
