That she is.

Basically, just find the folder the scene's/object's/prop's materials are in and override the files that way, or go to the surfaces tab and find the particular surface that is the image and replace the displayed image.

Oh, thanks for the reply....will have to practice this

Modifying the image via the surfaces tab is the fastest and most efficient method, but sometimes it is also necessary to adjust the Offset and Tiles settings.
