I've stored pictures in a database, and when the thumbnails are klicked a new window pops up (javascript, with the right sizes). The big picture is fetched from the database and "printed" in the new window using the PHP echo command (actuallt printing the string in the window). The thing is, the string is what actually is showed in the new window for all non-IE users. IE somehow understand that it's i picture being displayed, but ither browsers do not. You can look at it and see for yourself at www.fastmec.com (the site's in swedish).
Any ides how I make this work with all browsers?
