Resizing photo for header image

[ffs]

My forum banner is 1215px wide and 50px in height and I would like to put an image as a background; is there a shrink-to-fit or enlarge-to-fit code available that allows the banner to show the full image rather than just a right-sized part of it?

This is one image I'm considering, but it's only 612 x 384 px.

You can resize a background image using CSS Styling, but it will only work in the more recent browsers...

#banner { background-size: cover; }

Will resize an image to cover the entire cell, but, depending on the original width/height ratio, you will lose some of the image.

Or you can stretch the image to fit with...

#banner { background-size: 100% 100%; }
