Brilliant, many thanks. Just one last thing, something else. I have created a post and used the insert PDF block. Everything is fine except, when I view the post, it generates the text - 'Download PDF file here' - there is no link on this. There is a link on the title to go to full post and the PDF is viewed OK. I've tried to get rid of the text with no link. How can I either, delete this text, or get rid of the intro text and just have the title to go to full post? I've attached a screen grab.
Also, what is the best way to insert an image and put a link on that image. I can't seem to do this either and this seems so basic.
many thanks
