Edit images on website

We are looking for a freelancer to edit images on our website, which is on the Shopify platform. The website sells footwear and accessories. Some of the images are different sizes or have different colour backgrounds, which makes them look inconsistent. We want someone to go through the website and make changes to ensure that all products look similar.

The project includes a maximum of 80 images that need to be edited. The freelancer should have experience in editing images and should be able to make the products look professional and cohesive. We are looking for someone who can complete the project within a reasonable timeframe.
