movement in BB
today while cleaning off my bike and inspecting it all, i noticed there to be some play in the BB. when crank arms are parallel with the ground, they will move back and forth slightly. i just replaced the crankset and when i looked the BB i didnt notice any movement, and it seemed to be in good condition still. is there a chance that it could just be loose, or is it shot? its a square taper if that matters.
thanks for any help.
the picture is while looking down on the bike.

thanks for the help. is replace the cartridges easy? i'm still a novice in bike repair but want to be able to do most of it myself in the long term. i ride everyday (well, when i dont have too much school work). basically i dont want to screw anything up and then be out of a bike for weeks.
