how to lookup image from different excel

I am creating an excel workbook file with one of the column
containing a title of an image that is in another excel workbook
file, that excel file contained huge database of images how to
lookup images form that excel workbook file with their individual
title
Note: these are two different Excel workbooks. And the condition
is we can't merge file because imageDatabase file is so heavy
up to 25MB for that reason excel is get not responding or force
close.
file for example: https://drive.google.com/a/flygoldfinch.com/
