I am looking in the requirements for Zenphoto.

It says it requires Imagick 6.3.8

Where can I find this (I have searched and none of the websites have anything earlier that 7

Ubuntu 24.04

I found in my notes: sudo apt install php8.4-imagick -y

It looks like it install 6.9... is that OK

Older may work, but is not tested. Imagick otherwise is of course optional and often just can be better choice for image processing than the standard GD library.

Requirements list minimal version you need to have not the exact configuration.
So Imagick 6.3.8 is the oldest one that is recommended and everything newer is fine.

Indeed we had a + missing on that version version. I just updated the article.

While we're at it I also added a recommendation to us InnoDB as the database table engine as that has better performance for larger databases.
