I have multiple complicated vector images in a document with multiple artboards. Zooming and moving around can sometimes cause Illustrator to stall for a few seconds. I'd like to temporarily hide the high res images to decrease load on memory and make it easier for Illustrator to do things, but I'd like to have the images replaced by gray boxes or some indicator that an object is still there.
Is this possible? When I use the actual "Hide" function it seems to simply remove the objects visually.
