I've been told locks like this are harder to bump? Thanks.

Bumping, in very short, is the jumping of the top pins in a locking system such that they all clear the shear line simultaneously, thus allowing the lock to be opened. Wafer locks don't have top pins. Actually, they don't have pins at all. That's why they're called "wafer tumbler locks", not "pin tumbler locks."
This explanation precludes any response concerning the remainder of your question.
If your intentions really aren't criminal, which I see as completely possible, I would recommend learning to pick locks. As for the ease with which it can be picked... if the lock you pictured is the same brand or type as the one you are working with, it's not going to be easy to pick - you have two rows of interlocking wafers that play off of each other, making it very difficult to get the lock to set. The lock is a "full turn" variety, which means to open it, you will have to successfully pick it between 2 and 4 times, and a similar number of times to close it. This is a security feature found on many locks that go into service with older vending machines, coin laundry, change machines, etc. as while they are not impossible to pick, it is difficult, and you would need to pick it several times just to get it unlocked, thus making any criminal action take that much longer.

haha, thanks theopratr. just wondering, is there such thing as spring loaded wafer locks? Also, do jiggler type methods of lock picking more or less work by the same principle as bumping? That is, lining the pins up to the correct height. It seems that jiggling might work for a wafer lock then, if you were able to hit the wafers in the correct way? I'm having a hard time finding a good description of how exactly a wafer lock works, even what a "wafer" is in the context of wafer locks.
Go buy a cheap desk lock...it is a wafer lock...and take it apart. There are springs and wafers inside the plug. The wafers can be removed by prying them out. The springs may fly out when the wafer is removed or you may have to manually remove them. Then you can have fun putting it back together.
Before you dissemble the lock, separate the plug from the cylinder and put the key in the plug. Watch what happens to the wafers, they move so that they are flush with the edge of the plug which allows the plug to turn inside the cylinder, but only when the proper key is inserted.
Trying to bump a wafer lock would only bend or tear the wafers. When you look at the inner workings of the wafer lock, you will see what is being said here.
