If you want to get rid of an element in Plogger (e.g. the meta-header in the galleries), but don't want to change the Plogger PHP (or want to leave the functions in, in case you ever need them again, but don't know how to find the line in PHP to comment out), you can always use "display:none;" to hide the element from CSS-compliant browsers.
There are pro's and con's to the approach (like the fact that the function is still there, just hidden), and I don't want to argue about it. But it's a tip for those afraid to delve too far into the PHP.
