Images not displayed when master Plugin folder is moved

| testing on localhost Windows |

my plugins folder is moved to a diff location instead of default ‘/wp-content/plugins’.
now the problem is that the images are not being shown.

now looking at the image URL, its pointing to ‘/wp-content/plugins/wp-admin-graphic-password/images/..’.
so obviously, the issues wit plugins_url().

i added define( 'WP_PLUGIN_URL', __DIR__ . '\plugins' ); to my wp-config.php and thats fixed.

also i added sanitization code for effin windows:

$image_url = plugins_url('images/', __FILE__);
	foreach ( array('imagepath', 'image', 'image_url') as $var ) {
		$$var = str_replace('\\' ,'/', $$var); // sanitize for Win
	}

but now the images are not fetched at all (earlier it was showing broken-image/improper URL). i echoed $image_url and thats proper.

so now am guessing that theres something going on in SG_PrintCells() or other fn that i am unaware of..
but i left debugging here.. wud be good if theres a fix for this..

cheers..
