There is no need to check every request.

Check the process:

Supose that the images are on the home of the image gallery:

GET /Index.php -> served by PHP (by Apache) *
GET /scaleY/image1.png -> served by Apache (or LIGHTTP) **
GET /scaleY/image2.png -> served by Apache (or LIGHTTP) **
GET /scaleY/image3.png -> served by Apache (or LIGHTTP) **
GET /scaleY/image4.png -> served by Apache (or LIGHTTP) **
GET /scaleY/image5.png -> served by Apache (or LIGHTTP) **

*
Index.php check image files... If one of the images doesn't exists, it
generates.
If all images exists, no matters. Anyway PHP have to process index.php
so there is no overhead beyond a "if(file_exists))" in a foreach of images.

**
no PHP needed, images here had been always created.

Can anyone access to "/scaleY/image5.png" directly ? how? from where he
get the address?

From google? (google have to had visited the index.php) Or other search
engine? (IDEM).

Rgds.
