How can I get a picture from PhotoBooth onto Facebook?

[Is]

Hello! I was just wondering how it's possible to get a picture from the application PhotoBooth so you can upload it onto Facebook. I know it's possible because I could do it a few weeks ago, but not any more!

Basically when I go to the 'Upload Picture' menu on Facebook it comes up with a list of applications to choose the picture from, but PhotoBooth (along with most of the others, except one or two) are in grey so you can't click them. Why is this and how can I solve it?

Thanks very much!
