"What is this term DPI (dots per inch), really?
"It’s a measure of how many dots will be printed per inch. Keyword: printed. DPI, contrary to many ideas around it, does absolutely nothing when it’s set in Photoshop for images that are displayed on the web."
"On the web, pixels reign.
"If your image is 100 pixels across, it shows on screen at 100 pixels across. Dpi means nothing to a browser. While certain programs can interpret dpi, like Photoshop, InDesign, or even Microsoft Word, browsers don’t. So you shouldn’t worry about setting images at 72 dpi."
(The only caveat I would add to this article is that Photoshop by default seems to use dpi for text. So 10 pt font will appear differently in a 72 dpi file than it will in a 300 dpi file.)
