Rewriting my question on this issue. To use CFIMAGE in Lucee 7, it appears that I can downgrade the Image Extension for Jakarta EE (Lucee 7+) and use CFIMAGE.
What is the max version of Image Extension for Jakarta EE (Lucee 7+) for Lucee 7.0.4.34?
Is there anything special in Image Extension for Jakarta EE (Lucee 7+) 3.0.1.1 that would be worth running a release of Lucee 7.1.0.2 in a production setting?
And finally, I think what I was dreaming of is the ability for CFIMAGE to read HEIF files or at least get the metadata. Looks like that is still a no go.
