[QUOTE=gwpriester;522704]Yeah, I hear you, Paul. My thinking is when you export an image from Xara at 96dpi with a zoom factor of 100% it is 1:1 and should appear at the same size and resolution when you see it in a browser./quote]
My suggestion is that the browser couldn't care less what the dpi is. All browsers care about are pixel dimensions.

Ah, maybe it was this. For print, what matters is the actual pixel dimensions. So if I export an image that on the screen is 960 x 768 at 300ppi the actual size in pixels is 10" x 8". But if I take the same image an post it on the web, the size is 3000 x 2400 pixels, larger than most monitors
yes, that's because for print purposes you specify a physical size and the number of pixels to create per inch.

I think I'm failing to get across that dpi is irrelevant online. Pixel dimensions rule online and dpi is totally ignored for images and doesn't exist in some formats.
