I have created an "Add Question" content-type node which lets users ask questions. The questions have a title, image attachment option, and the content.

I am showing the questions which have image as a block by filtering it as "Content: Photofield - list True" in Views. This way, only the questions which have images attached to the question appear in this block. Photofield by the way is the content type.

I want to create a new block which only shows the questions which have no attached image. I have done filtering this block view by keeping filters as "Content: Photofield - list False" but in vain.

There's also some expose option and I did some messing around with it too without coming to the result I want.

Can anyone help?
