UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? Image scaling in IE

Hi

I have set the maximum width of images to 700px under 'Max width for images used in posts?' in feature settings. This works in Firefox but does not in IE. In IE the images which are the 'right' size in Firefox cause a horizontal scroll bar.

Anyone know why this is the case and what I can do to fix it so it scales in both browsers?

Using v7.5.3
