Hi again, I'm having another problem as you'd of guessed, basically I've added a header php file into my default theme folder, then used includes to add my header to all of the files withing this folder so that my header shows on the top of every album page, this works a treat and keeps the site looking right.

the problem is that the header shows up perfectly on every page, other than when you have more than one page of albums, when you move to say page 2 or 3 and so on the header doesn't appear, it momenterily shows a broken link icon then all is blank, have tried aiming the hrefs to different direction but with no luck, any ideas??

any help will be appreciated.

Quite strange, I have the same structure with an header.php loaded in every page, but I have not the same problem.
I'm loading it simply with the line:
``
in every script of my theme.

it appear to only be in the php generated html pages that its happening?

All Zenphoto theme pages are php generated html pages actually. You will have to use the right path and probably there is an error somewhere. Without that we probably cannot help. It is certainly working as bic said and we also use it on our own site.
