A hanging curveball is a curveball that is thrown in a way that makes it easier to hit. A good example of one is a slow curveball that is thrown down the middle. If you get one of these babies thrown to you while your at the plate, swing at it. It is an easy pitch to crush for a dinger or at least a double.

The curveball is a breaking pitch in baseballthrown with a characteristic grip and hand movement that impart down and/or sideways spin to the ball. It is therefore considered a type of breaking ball. Contrary to a fastball (which has only back spin), the curveball has a diagonal spin that creates a wake behind the ball, making the pitch drop on its way to the plate. A curveball is used to disrupt the opponent's timing. While it is a good pitch for doing so, it is also a dangerous pitch to throw. The increased topspin of the ball has the potential to gain tremendous backspin off of a batter's bat, giving it much added distance if well hit. For pitchers, it is better to throw a straight breaking ball, one that breaks from high to low as opposed to side to side. The simple argument for this is that the batter has 33 inches to hit a side to side pitch, while only one inch to hit an up to down pitch.
The main difference between a slider and curveball is the way that they move. Imagine your throwing a slider at a clock. It would go from 3 to 9. However, if you were to throw a curveball at a clock it would go from about 1:30 to 7:30.
The best thing to do with old pictures is to hang on to them. If you do not want to you can throw them out with regular trash.
Baseballs curve due to the pitch that is thrown. There are many different pitches that can be thrown to make the ball curve, such as the curveball, slider, gyro and many more. Each pitch has a different grip and a different way to throw the ball. You need to use your wrist to whip the ball and cause the curvature.
I believe the best way would be to throw it in the trash.
