96 or 72dpi?

[Paul.Tait]

I have always used any graphics for the web at 72dpi although I know most (if not all) PCs display at 96dpi. Now, with many of the current Mac screens running at 96, should I be producing web graphics at 96dpi as standard, or does it really not make any difference either way?

I'd be interested in your opinions.

Thanks

I still use 72 dpi.

It makes absolutely no difference. Web browsers do not look at the file's resolution. They only look at the total number of pixels. The resolution information is discarded; the image is shown on the screen at the resolution of the computer monitor, no matter what the resolution of the file is.

If you have an image that is 300 pixels by 200 pixels at 72 pixels per inch, an image that is 300 pixels by 200 pixels at 96 pixels per inch, and an image that is 300 pixels by 200 pixels at 3,000,000 pixels per inch, all three images will look identical on a Web browser. The Web browser does not even look at the image's resolution at all.
