Macro for Name Generation from Product to Product with Sizes and Filenames

I would like to have a Macro to go from the first tab called "Start" and end up with the second tab "End" automatically. BAsically I need to take the product on each line under Tab Start and reproduce it for sizes 35-41 always ending with "-(size)". Then this new Product with Size needs to be multiplied one below the other for as many times as I have pictures (number shown under column B of the tab Start). Next to this value in column B of tab End I'd like the same name listed again but with the number 1, then 2, then 3, etc. as needed and the extension .jpg. I think it sounds more complicated than it is but I couldn't figure it out.

Thank you soooo much for your help, this will be a life-saver!!

Best,

Diego
