BBM Groups saving photos to phone

new here, but I need your guys' help. Can someone(anyone) please confirm for me that BBM does in fact save group photos to your phone. members of a group I was a member of(nothing inappropriate in nature) thought it was a good idea to post alot of dirty photos in the group album which somehow saved onto my device or memory card. Long story short, my girlfriend found the pictures and I feel awful about it and can't really explain to her that it isn't me intentionally saving the pictures, nor taking them.
:(
they are being saved to a folder called BLACKBERRY MESSENGER then in a sub folder of the groups name and I just need somebody to confirm that this does in fact happen, and it isn't me intentionally saving them.
thank you so much.

well, I'm not sure where the pics are saved.

However, I tried to save a pic from a group to my memory card and only happened after I selected save pictures on group details.

then I was able to select the picture and save it on my memory card.

If you select the Group, Hit BB button, select Group Details, In Group Options there is a "Save Pictures" option.
