Is there a freeImage() ref count?

My Performer application allocates and frees textures several times.
Some of these these textures share images. On occasion, a texture
image is freed with pfTexture::freeImage() that is being used by
another texture and an undesirable "white image" appears.

Is there any way to check and see if an image is being used by another
texture before calling pfTexture::freeImage()? An image reference count
maybe? Or is there another way to avoid this scenario?

Thanks in advance,

Frank
