Well, those things happen, no problem.

IMAGE_NUM and IMAGE_NUM_CURRENT used to be the same. Do you (or Ernesto,
maybe) know what the difference between them is and whether or not
IMAGE_NUM should also be set to the new value? I was just wondering
about that when I was checking the code. I couldn't find any other
occurence of IMAGE_NUM in the code but only some documentation at [1].

Relevant lines:
>  			$GLOBALS['TSFE']->register['IMAGE_NUM'] = $a;
> -			$GLOBALS['TSFE']->register['IMAGE_NUM_CURRENT'] = $a;
> +			$GLOBALS['TSFE']->register['IMAGE_NUM_CURRENT'] = $a+$imgStart;
>  			$GLOBALS['TSFE']->register['ORIG_FILENAME'] = $totalImagePath;

cheers
Ingmar
