Trying to upload a CMYK image results in a "String org.apache.commons.imaging.ImageReadException:4 components are invalid or unsupported" error. Apparently the commons imaging jar in lucee was last updated in 2014. More discussion on this at https://dev.lucee.org/t/string-org-apache-commons-imaging-imagereadexception-4-components-are-invalid-or-unsupported/2501
I'm attaching a file that will kick back this error when uploaded. Fingers crossed this site doesn't use Lucee so it will upload
