Problems with picture position.

[Gregor Skrt]

I'm writing my thesis in Lyx. It's a great for long texts. First thanks 
to all developers of Lxy !

I have one question concerning picture floats. I have a picture that's 
quite long and doesn't fit between borders very well. It seems like Lyx 
is obeying borders that I've set in document settings and ads some free 
space between border and picture on left side. Is there a way to use 
that free space too ?

I'm using article class.

Thanks for your help !
