Examples

Due to the config given by route (additional), this will serve the Image emvicy.png from the public folder /public/ in different variations:

<!-- request image with original width + height; auto-redirects with proper dimension ratio request if necessary -->
<img src="/idolon/emvicy/png/">

<!-- request image with width of 150px; height will be calculated; auto-redirects with proper dimension ratio request if necessary -->
<img src="/idolon/emvicy/png/150/">

<!-- request image with width of 150px and height of 172px; redirects with proper dimension ratio request if necessary -->
<img src="/idolon/emvicy/png/150/172/1/">

<!-- request image with width of 150px and height of 150px; NO redirect - serves it as it is requested -->
<img src="/idolon/emvicy/png/150/150/0/">
