Does anyone know how to resize images proportionally using JavaScript?
I have tried to modify the DOM by adding attributes height and width on the fly, but seems did not work on IE6.
To modify an image proportionally, simply only alter one of the width/height css properties, leave the other set to auto.
image.style.width = '50%'
image.style.height = 'auto'
This will ensure that its aspect ratio remains the same.
Bear in mind that browsers tend to suck at resizing images nicely - you'll probably find that your resized image looks horrible.
