DPI doesn't really matter until you send a file to your printer. I believe the standard for Windows nowadays is 96dpi, and you can change this, but all it does is alter the size of images/fonts, etc on your display. How you size your images depends on your target audience. I believe it's best to size your images so that people can view a complete slide show without having to scroll to see the whole picture. And you have to watch the file size as well, especially if you expect alot of visitors who have dial up connections. As recently as 1999/2000 you had to design web pages to accomodate computers with 800x600 displays and 28.8 dial up connections. That meant a max image size around 440 or 540 px long, allowing space for page headers, a navigation interface, and the ability to display both vertical and horizontal images without scrolling the page. Today, it is safe to assume 1024x768 as a minumum with a much higher percentage of people using braodband. Allowing for the overhead mentioned above, I think it's safe to deploy images at a maximum size of 640 pixels on the longest edge. As to compression, I struggle to see much improvement in image quality much past Photoshop's "jpeg 60" quality. You can see improvements if you look very close, but the differences are small, as far as I can see, and only apparent under critical examination. - --Jim - ----- Original Message ----- From: "Stuart Phillips" <stuart.phillips@rcn.com> To: <leica-users@mejac.palo-alto.ca.us> Sent: Sunday, October 27, 2002 9:56 AM Subject: Re: [Leica] Re: web sizing images > Actually monitors vary; 72ppi was the figure for the original mac.
