Testing image size at upload

I need to upload image with exact size. 1920 x 1080
Is there a way to create an alert at upload that is testing the image pixel size? If the file size is different do not upload and show à error message saying “Make sure your image is 1920 x 1080”
How would you do that?

I’m pretty sure there’s no way to do this yet. I’ll be working a lot on the way images are served (via Imgix) this summer, and putting in a request for more Imgix parameters.

Why do you need the image to be exactly 1920x1080?

Hi @lonetour,
Thanks for your quick relply.
I am gathering data from graphic designers to feed visual content into my pages.
I need to make sure that they are in the good format as they are displayed in the page.
Ex: Logo size 300 x 200, or Facebook Banner 851 x 315, … I am just looking for a way to check the file before upload to avoid mistake. If you have any idea, let me know


I found this, but haven’t enough experience to help, but look not complicated:
