How do you get your Logo to Resize

[Guest]

Oscommerce seems to handle difference size screens within any problems. However, how do you get your logo to auto re-size based on visitors screen size like the rest of oscommerce does.

 

Have uploaded a logo and on some size screens it fine, on others it goes over the end of the screen and others its too short.

 

Any help would be most appreciated.

 

Thanks,
