Problem with text wrap around image placed over coloured background

Hi all, hope someone can help. I have a master page spread which is black on one side and grey on the other. I am trying to add a picture with text wrap and text to go with it, on top of the grey page. The picture is visible, but the text is not, unless I tick the "ignore the text wrap option".However, if I do this, the text goes over the picture and doesn't wrap around it like I want it to. I can't seem to have a coloured background page AND an image with text wrap and still see my text.

I hope that makes sense!
