have place a number of aerial photos onto a site diagram. have linked them via an absolute path. for some reason the photo boundary is displayed but the photo is not. if i change the display of the photo from original colors to B&W, or vice-versa, the photo is displayed - until i refresh, and then the photo disappears again. i've checked everything i can think of to make sure something is not turned off or otherwise not set correctly by setting individual options to different settings. what else could be going on?
