Include issues

[sdkramer]

Okay I have a several pages that may be in subfolders each of these pages has an include on it how do i do this without putting the file in each directory.

example

index.php has an include and the includedfile.php is in the directory with maybe picture.jpg in it

now in
/subfolder/index.php has an include, but refers to ../includedfile.php problem is the includedfile.php has a reference to picture.jpg which is not in /subfolder

How can i solve this without having to change the included file in a hundred diffrent subfolders? No frames.
