It works! Thank you very much!

Hi,
I am using JoomGallery 1.5.7.3 and Joomla 1.5.22.
I wanted to remove text Total images in all categories and Total number of hits on all images. I searched in this forum and found a solution. As I understood, the solution is to modify joomgallery.html.php. But I can not find this file anywhere (I looked in Components, in Administrative->Components, and in all subfolders there).. I think that this "problem" is because I am using other version, and the name of the files are not same.
Am I right? Please tell me how to menage this in my version and what I need to remove and from where?
Thank you in advance.
