Please run your site though an accessibility validator like ACA. At the very least make sure all images have an alt attribute! I feel like so many devs ignore accessibility even though it's not really that hard.
It really tends to me an afterthought. A lot of places that i've worked for, accessibility is never factored with estimates. If it does make it, it's a rushed job, or it never makes it and after few complaints, it's added as needed.
