Each Browser supports PNG. The only problem is with transparent PNGs - but really only transparent PNGs, not normal images without transparency. But there are also workarounds for this problem available (please search for PNG within this forum).

GIF supports only 256 colors. PNG supports 16,000,000 colors.

PNG supports two kinds of transparency:

First is palette based transparency works like GIF transparency does. You designate a color to be the transparent color and anything that renders the PNG knows not to display that particular color.

The second is alpha transparency, where there's an actual alpha channel included with the image. In this kind of transparency pixels are formatted as RGBA instead of RGB (i.e. a color and how transparent that color should be).

As far as I know (but it's been a while) the first kind of transparency works in IE, but IE can't handle alpha transparency, so it ignores the alpha channel entirely. As has been mentioned there are tricks you can use to make IE render alpha channel PNG's properly in a way that other browsers that know better entirely ignore.

For some reason this method stopped working with Xara Xtreme 3.2.4.3017.
I used it successfully for about 20 of the same files with minor changes.
Today, all I can export is a blank image. If I turn on the invisible line, it will show up on export. Somehow the first layer is not being picked up for exporting.
The only work-around is arrange-> create a bitmap copy.
Any suggestions?

Thanks, John. Color Depth got changed on my export panel.
I thought there was a random bug.

I think the default is alpha transparency, but don't quote me. I have played with too many versions to remember what is the default anymore.
