hey, not sure if this is the right place to put this post but...
i have an html file and would like to include the index.php from my gallery inside it. what's the best way to go about doing this? any help would be appreciated.
Try to use an IFRAME : something like that :
<iframe
height="550" frameborder="0" width="100%" scrolling="auto"
src="http://coppermine.sourceforge.net/board/index.php?board=38.0"
allowtransparency="true" name="FrameCoppermine">
</iframe>
Change with your own URL.
My exemple (http://www.pays-dignois.com/galerie/index.php?file=minicms/cms&id=20).

I believe what you are asking is about creating a custom theme (you want to display coppermine in your webpage)
It is quite simple to do. Either you can use an iframe (search these forums for how to do this) or copy and rename your chose theme (I'm uscing classic as an example). Simply then include everything inside the body of the classic them inside the table in your html page then select this theme in the cpg config.
eg copy themes/classic to themes/yourtheme
take your html page and place everything from themes/classic/template.html inside the 'body' inside a table or div in your htaml page wherever you want the gallery to display then save this as themes/yourthem/template.html
select yourtheme in the gallery config.
Sorry if that sounds simplistic but it really is that easy.
