Batch editing product photos

Hi,

We edit many thousens of product photos every year in PS för our e-commerce. We get product photos from brands and distributors in many differrent styles, sizes and format. In PS we use a simple template that has correct canvas size with lines that marks where the product should be in terms of size. This to make everything equal and conform undepending on brands. We sell for example skis and want the same look for all skis. Now with the latest version it is very easy to remove background if needed but the size/proportions of the actual product in the picture seems very hard to find a ''less manual" workflow for.

Attached a ready processed file to give you an idea of the outcome we need.

Anyone with some ideas? Very much appriciated.
