A graphic object is a set of defined points and vectors, a mathematical formula, if you will. As such it can be scaled and changed with no loss of quality. Think MacDraw or Adobe Illustrator.

An image object is a bitmap. Each pixel in the bitmap has a defined color (and optionally a transparency value). It will rapidly lose quality if resized or reshaped drastically. Think MacPaint or Photoshop.

You can create an image from a graphic by using the import snapshot command in LiveCode.
