Filepath to Images Not Correct

@benedikt Mo

I made a routine to fix filepath to images as SpillnerDesign said.
I have tested it with the version 1.8.2 of Nextgen ScrollGallery, but I believe it fix BMo Expo plugin in the same way.
I hope you would like this routine.
Thanks,
Miguel
side note: this is not related to “divide by zero” error.

/* the problem
 * I have noticed that scrollgallery create links to images using the following code
 *	SCROLLGALLERY_SITEBASE_URL . "/" . $picture->path ."/" . $picture->file
 * This works in almost all unix environments, but, in windows, $picture->path has the absolute fullpath to the image file and the link become invalid.
 * Like that: http://mysite.org/wordpress/E:/Home/httpdocs/wordpress/wp-content/gallery/2013/dsc_3823.jpg
 *
/* the goal
 *In the example above, E:/Home/httpdocs/wordpress/wp-content/gallery/2013 is the $picture->path and needs to be adjusted.
 *My goal is to remove the absolute fullpath part from the result of $picture->path.
 *
/* the strategy
 *	I have noticed the part I want to remove is the absolute full path to site I know as ABSPATH.
 *	Then I made a routine named nggSGStartPath that remove the ABSPATH from $picture->path and inserted the code
 *		$picture->path = nggSGStartPath(SCROLLGALLERY_SITEBASE_HOMEPATH,$picture->path);
 *	at the right place.
 *
 *	There is one caveat, I mean, ABSPATH is like E:\Home\httpdocs\wordpress/ (note the first and the last slash) and $picture->path is like E:/Home/httpdocs/wordpress/wp-content/gallery/2013.
 *	I have to deal with it.
 *	We believe this routine does not break unix hosted systems.
