Hello to everyone and thank oy in advance. I hope that what I ask for is doable.
In a sheet (excel 2013) I keep a list of images belonging to specific folders.
As you could imagine I have copied the path of each image and then used the function HYPELINK(CELL) to turn them into clickable hyperlinks.
Now what I would like to get is a pop-up of the image when hovering around each cell.
Is such a feature achievable? To somehow use the link address of the hyperlink and get just a pop-up of the image file when hovering the cell??

Hey Georgiboy...Thank you for your time.
I got to the file and I try to apply the specific

Excel Formula: 
=HYPERLINK(MouseHover(D4);"Pic 1")

But no result...
I also noticed the code on the sheet

VBA Code: 
Option Explicit

Private Sub Worksheet_SelectionChange(ByVal Target As Range)

End Sub

Does the above play any part to the function etc???

Just figured it out and ...... W-O-W!!!!!!!!!

We need

The code for the sheet
The module
The Form & the code for it

AMAZING!!!!!!!

tHANK YOU SO MUCH!!!

a couple of notes though

Can we make the form disappear after x seconds or/and force to close when hitting esc button???

Another issue I notice is that when I need to enter new data in the table range I use (to add a new row, with image path, etc), the form pops up and keeps popping one image after the other forever..The only thing I can do is ask task manager to close the entire Excel (All Open Workbooks).

Is there any way to stop this ?

I guess you are aware we can add pictures to cell comments. That would be much easier and cleaner than using the Hyperlink trick ... Obviously, adding pics to comments with would only work with static pictures as there is no built-in way of detecting when the mouse hovers over cells.

I am not sure which exact scenario you have.

Anyways, for dynamic pictures using the hyperlink approach, I have played around a bit with it and have come up with the following code.

This code should prevent the form from popping up repeatedly when inserting\deleting rows and it should also allow for dismissing the form when hitting the ESC key as requested.

Note: The UserForm is left blank with no controls and has no code behind it. Also, needless to say that will need to change the image files paths in cells D9 and D10 to suit your needs.
