Need help to determine If I'm asking something impossible from the devs working on my web page.
First of all, I apologize if this is not something I should be posting here, mods if it's not permitted feel free to delete this post. Second, I ask for forgiveness if my English is not the best, not my first language.
I hired a group of devs to work on a simple e-commerce for the family's hardware store. Something simple that could allow us to gather clients over the web in and outside our state. Everything seemed to be fine after initial talks where we explained what we needed, basically a simple web where we could display our products and have a simple way for clients to generate orders we could then process in the store. So far so good, until they told us we had to manually modify the pictures for each item in Photoshop to be 500x500 and to make them 1:1, Before uploading them. Something I found absurd since most modern pages can take most jpgs, pngs, resize them, change them into whatever aspect ratio needed and convert them to webp. The dev team went on the defensive on this, saying it was hard to implement and that this was outside of the budget.
For more information they told me they are making the page on NestJS for the backend and Next.js for the front end.
Am I being unreasonable?
