The PHP code that scales the picture, where the variable classes is an array, can select the settings specified in any number of INI files:

This is an INI configuration file, the above code will read this file in the image location, can be multiple.

; Translate the image format using the original image size
[Translation]
Width=0
Height=0

; Stretch the image to the specified size
[Stretch]
width=800
height=600

Zoom the image to the specified width with height auto size
[Autoheight]
width=740
Height=0

Zoom the image to the specified height with width auto size
[Autowidth]
Width=0
height=380
*/?>

Note: The INI file is interpreted as a comment file using PHP, and nothing is output, which is intended for security reasons. Instead, it is a comment for the INI file.
