Description
http://plone.org/products/plone/roadmap/123
Plone should automatically work around the bugs in Internet Explorer so that we can start using transparent PNGs for the icons.

State
being-discussed
Motivation
Currently, there is no way to use PNG images with alpha channel information in Plone running on Internet Explorer.
We'd like to switch Plone's default icon format to PNG — but before we can do that, we need to implement one of the workaround implementations that already exist.
Proposal
We should look at something like Dean Edwards' IE7 or a different solutions to fix this problem.
I'd like to include IE7 wholesale in Plone, but our last attempt at this resulted in a massive slowdown on loading a page, so we'll have to re-evaluate and do some tweaking if we want to include it.
Risks
- Fixing this for all the icons on a standard page might turn out as too slow.
- We should make sure this works with images in the CSS classes too (background images etc)
With Plone 4 we have switched over to png icons. Since IE6 support isn't a requirement anymore, no special JavaScript solution was deemed necessary.
