I have a website that uses this image on about 30 page: "logo.jpg".
The image is a JPG but it needs a transparency, so I really need to replace it with a GIF image.
Can I rename a file called "logo.gif" to "logo.jpg" even though it is NOT a jpeg image? If I do that will all or at least most browsers display it correctly? Or does a gif image have to have .gif for the extension?
I am too lazy to change the HTML code in 30 pages to gif instead of jpg.
