Hi!
I upgrade to the last version of XAMPP (7.4.1) and it's not have JPEG Support in Graphic Library.
I see that this Library is the same version (GD 2.2.5) of the previous XAMPP version.
It's a bug?
I use macox platform, i can't see if this bug is in other platforms..
I create a fresh install and the same result.
XAMPP Version: 7.4.1
OS: macOS 10.14.6 (Mojave)
