G2 + Drupal 4.7.5 - "?g2_GALLERYSID=" in image path?

Quick question ... i have G2 (lastest) installed with drupal 4.7.5 - when i view the address of the image displayed it gives me the path with "?g2_GALLERYSID=" behind the xxxxxx.jpg

for example:
page:
http://www.swfmas.com/v/users/wiszmaster/IMG_3488.jpg.html

Image path:
http://www.swfmas.com/gallery2/d/1697-2/IMG_3488.jpg?g2_GALLERYSID=1d61b35cc17d9e723ad0be8df6eb0d94

But how can i get it to suppress everything behind the image file name

This is how i'd like it:
http://www.swfmas.com/gallery2/d/1697-2/IMG_3488.jpg

Gallery version = 2.1.2 core 1.1.0.2
PHP version = 4.3.11 apache2handler
Webserver = Apache/2.0.52 (Fedora)
Database = mysql 4.1.16-max, lock.system=database
Toolkits = ArchiveUpload, Exif, Getid3, NetPBM, Thumbnail, Gd, Dcraw
Acceleration = none, none
Operating system = Linux 2.6.10-1.770_FC3smp #1 SMP Thu Feb 24 18:36:43 EST 2005 x86_64
Default theme = matrix
Locale = en_US
Browser = Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en) AppleWebKit/418.9.1 (KHTML, like Gecko) Safari/419.3

Thank you guys,
