Hi,
I would like to ask about how to, randomly, hide a file path using PHP and what is the technical name of such process.

For example:
mywebsite.com/imgs/someuser/img.jpg
to
mywebsite.com/imgs/nddsfdsfgdfuu4923fdj3er982/img.jpg
while the value nddsfdsfgdfuu4923fdj3er982 should be randomly changed every time the img.jpg is requested.
