turkeylegs on "[Plugin: TablePress] Insert image won't work"

I have downloaded, installed and activated TablePress and am attempting to insert an image. I click in the cell and move the cursor to insert image, click and get a message that tells men to click in the cell where I want to image and it will open the media library. So I click in the cell I want, click insert image and get the message again. I suppose I am doing something wrong, but can't figure out what it is. Please steer me in the right direction.
Thanks,
Joe
