PSA For Web Developers Who Only Test in SafariFiled on Mar 28, 2008 by AnthonyDiSante
Here’s a Public Service Announcement for web developers who only test their websites in Safari.
Safari happens to do high-quality (but slower) image scaling, so that if the dimensions that you specify for an image don’t match the image’s actual dimensions, it’ll still look decent. But other browsers do lower-quality (but faster) image scaling, which makes such an image recognizable, but jaggy.
This means that the 1000x1000 pixel image which you’ve stuffed into a 50x50 pixel spot on a web page looks like absolute crap in most browsers, even though it looks decent in Safari. So instead of trying to stuff an image into a container of the wrong dimensions, you should rescale the image in your photo-editor first, then specify the correct dimensions in your web page.
