nowadays it is possible to remove the sidebar from a single page and thus "use the whole width" for that page. However, a full-width image on such page appears to be the exact same size as it is with the sidebar.
Is there any way around this, so that I could display a wider (950px?) image or iframe on a page without sidebar?
I have the same question.
Thanks man! This works great! Also works on images, although you have to check that the image width is set wide enough. e.g. .jpg?width=1000 and then width="100%"
Great, thank you very much Robert!
