Code to get image file name in table on Mouse Click

Rowan, I was not able to get the code to work to extract the image src from a mouse click in a table. Java Script is still a bit confusing for me at this time. If it was Visual Basic Im sure I could do what I wanted, but not with Js. If you get it to work I would appreciate the sample code and I would even be willing to pay for it.
WIX has the code for what we want, I wish they would share. The see the example, create a collection (database) and populate images in the column (property type image) there and then hover over that image you will see what we want. The hover creates a large size of the image to be displayed in a box with the file name and the size in pixels.
