best dpi for web design?

dpi settings are irrelevant on the web and will be ignored by web browsers, which will display your images at 1:1 pixels. Xtreme may internally think that a pixel is 1/96 of an inch, but that information is meaningless when it comes to exporting a web page.

if i buy some pictures @ 300 dpi does xara change them to 72 dpi or 96 dpi?

Xtreme exports images at whatever pixel size you see when you drop them on your page. When exporting for web, it tries not to give any dpi information, as it's irrelevant. (ie. no pHYs chunk in PNG.)

As Jimi said, typically the use of having bigger/higher-res pictures is so that you can resize and crop them to fit the size you want. Smaller images tend to look poor/blurry/deformed when you try to scale them, so if you've got a little image you've nicked off a web page, you are pretty much stuck with that size.

What this means in terms of images is that if the image is 640 x 480 pixels, it will show as 6.666" x 5" on a windows machine and 8.888" x 6.666" on a Mac. If you want it to display smaller then you will have to physically reduce the size of the image. You cannot change the resolution .... (Ignoring the silly 120 dpi option of course) ....

As Bob said, the actual dpi of the image is irrelevant only it's physical size in pixels matters.

Exactly so don't think about dpi so much when you are dealing with web, as for the most part dpi is irrelevant. The only thing you need to know is that it is better to save your images out of Xara at default screen resolution which is 96 and then go and convert them to 72 dpi without actually resampling the image using a batch converter like thumbs plus. This way if you need to use those images in Flash they will import correctly. Actually Adobe Flash is the only web app I know of that pays attention to pixel dpi and will not display your images correctly if you are saving straight out of Xara at 96 dpi.

Why convert to 72 dpi? The Mac hasn't used that resolution for ages.
