Hi Tom,
I’m currently working on this site: http://decadentretreats.gowoof.co.uk/
That large picture is a slider. I’m trying to get the logo to sit in the middle of it at the top. I’ve use the page header content > advanced to merge with site header and place content behind header. That has the effect of filling the top of the page with my slider but the logo vanishes.
I’ve tried swapping the logo from png to a jpg (just in case of a corrupt file) – no joy.
Email me if you need a login.
Cheers, Gareth
