show hide images anchored to a cell v5 calc

after anchoring images to a column of cells, they are all on top of one another and there are more than the given choices of one back, one forward, top, bottom, etc. how to hide them all, until i park on the column /row value to obtain the desired image. [while parking the mouse would be ideal] clicking would do and clicking again to rehide. would be acceptable. I don’'t want to hide the entire column
