When adding a picture to your signature please be considerate to those that have a slower connection. It also becomes an eyesore when your signature is always 3x larger than your post and It makes things difficult to read. One signature of a reasonable size is fine but stacking numerous pictures in your signature to create a whole art gallery is not. Please nothing bigger than 600 x 130. That space is more than generous to show off your artistic abilities. Also, your total signature space is 600x130, meaning all your signutures and/or adornaments must be in that space.
The option to turn signatures off is also there for those who don't care about all the perty pictures. Go to your profile > Look and Layout Preferances > > Don't show users signatures
