Data Entry, Excel Spreadsheet, Assign Photo Images Into Excel

I have 850 products in an excel spreadsheet. Each product needs the correct image put into the image column in the spreadsheet. You will need to find the correct image from 2 different lists. To give further clarification, each image has part of the product code in the image link in the lists provided. For example, it may include 'Air [login to view URL]' as the image. In the current spreadsheet there is a product, SCDM2 that this would be the correct product to go with that image. Another product may be: Air [login to view URL] where it would be the image to go with product code SCDM6. This is the same type of format for all of the 850 products that need the correct image assigned. I need this done asap. Attention to detail is very important.
