No 'upload' button when adding company logos.

With the recent site update, i've been given semi-admin privileges on some pages. I tried uploading a logo to a page that didn't have one (http://getsatisfaction.com/pc_world_uk), but you only have the button to choose a image, there isn't a button to actually upload it.

I tried picking a image, then clicking 'Save Logos and Badges', but it also didn't upload the image.
