Rotating image on its center

[irispix]

Hi again,

I have 4 images layered one on top of the other.
On the monitor, each image occupies one corner of the screen.
I have set them up so that each rotates independently (but on its own location, I thought).

The peculiar thing is that, as each rotates they move location (slightly).
My question, how come they don't rotate on its own center?
I tried the "anchor" option but they don't stay put.

Each image will rotate around an Anchor Point. If the Anchor Point is some place other than at the center of your image, the image will move around it rather than rotate. Make sense?

By default, the Anchor Point is in the center of the image's canvas (which may or may not be at the center of the image -- if the image is off center in its PSD file). If it's off-center (as it sounds like yours may be) you may have to tweak the Anchor Point until it's at the very center (the axle) of each of your rotating images.
