Higher DPI images fail to upload

[tommyneu]

Images that are have a high DPI and are optimized for print will fail to upload and cause a 500 error message.

We might need a check the height and width so we only accept images below 1080x1080 in size

Any reason for 1080x1080 in particular?

More testing will need to be done but a 1080x1080 was a height and width that worked today compared to the 4500x4500 that was throwing the error

This is where the check would live

This might be an issue uploading PNG images
