Is it possible to check for PNG support with jQuery.Support?

Question

My question is regarding the jQuery Support system.

I\'d like to know if it is possible to tell whether or not the browser will support semi-transparent background P

Answer 1

I think that is simply not possible, after all, even IE6 shows the transparent png's, it just does not show the transparency; all browsers "support" png's so you can´t check for that.

If you could get the color of a specific pixel on a page, you could of course, but it seems that is impossible to do.
