Show cell value(text) in comment box text, or mouse tool tip on an gif icon

I have a spread sheet were the area is getting very limited. I need to insert a small icon and when the mouse goes over (like it does in a form tool tip) will show the value of a cell (text value) located in another sheet in same workbook, or I was thinking inset a comment next to the icon and link the comments of the comments text to cell with the text value.

I've look the properties of this to objects and can figure it out.

Any help will be greatly appreciated.
