Limit Uploaded Image Dimensions

is there a way to limit the uploaded image dimensions? We have the multivendor version and nearly half of our vendors are uploading images that are way too big.



Is there a way to stop this or reject the image if it is above a certain dimension?



Thanks

Set the limits that you want.

Thanks. I’m guessing if I set the field 'Detailed product image width ’ to 800 then images will only be 800px wide (if originally bigger). Is it for images uploaded after this setting is made or for all images.
