What is the best way check if file exists in module/img folder

[Amazzing]

I have a module with /img subfolder, where images are stored in the following order: mod1.jpg, mod2.jpg, mod3.jpg etc.

admin.tpl is responsible for displaying informations in backoffice.

So, my goal is to display imageX.jpg through admin.tpl if it exists in module/img/.
(X variable is accessed by {$myid} in admin.tpl)

I know I could use {if file_exists...

But what would be the best way to define the relative location of module/img folder?

I have seen this topic. And if you look carefully, you can see, that I even left a reply there in march 2013.  

My question was about defining the relative location of module/img folder.

 

Anyway, I chose another way, and decided to check if file exists in php and after that assign a corresponding value to smarty.

have you tried with {$content_dir} variable as a path to main directory shop? it's worth to check it with this one
