How to repeat the result of the CONCATENATE function a certain number of times in an exel cell with an increase of one digit?

Question

Database

Hello.
With zero knowledge of exel, I'm trying to create a database for my store, for the most part google helps, but there was a question that I could not find an answer to:
Let's say in column A, in each cell I have numbers from 3 to 10 - the number of photos
in column B is unique item number
column C should be formed based on the quantity in column A, and the number from B to the address (I have links to images), namely if A is 2 - B1;"/";"1";.jpg" ;",";B1;"/";"2";".jpg"
with a picture it will be clearer what it is about,

that is, I need to clone the link separated by commas as many times as indicated in A, I hope I explained it clearly)
please tell me how to implement it?
