How does William Shakespeare use imagery in King Lear?

Examples of Imagery:

"Come not between the dragon and his wrath."

"How sharper than a serpent's tooth it is / To have a thankless child!"

"Poor naked wretches, wheresoe’er you are, / That bide the pelting of this pitiless storm, / How shall your houseless heads and unfed sides, / Your looped and windowed raggedness, defend you / From seasons such as these?"
