This is a very easy job, although time consuming. We have several arrangements with manufacturers and they constantly upload better images for their products ( I.e Larger size, Better resolution, HD version, Full screen Versions, etc... ) and our website is aroud 4000+ products.
Unfortunately, we do not have a way to massively update pictures thorugh a CSV and it has to be done manually, one product at a time.
So the task consists in that we will give you a manufacturer to work with, and you will work with them to obtain the new catalog of pictures, then you will go into our store admin panel and upload the new product pictures ( the updated version) to each and every product that matches the manufacturer we gave you..
On average, we're talking about 100-500 products per manufacturer. So you will have to obtain and replace around 100-500 product pictures every time we give you a manufacturer to work with, so it shouldn't be extremely complicated
