Calling an image "alt text" for use in a macro?

[Cheshire]

Hello,

I'm hoping there is some way to call whatever text is stored in the "alt text" field of images placed in an excel sheet for use as a variable / string reference in a macro.

The "alt text" will not be changed in any way by the macro.

Any help on this would be greatly appreciated!
