Adding random files as external libraries to be accessed via scriptcase

Hi,
I’d like to include public library files as ttf fonts or png images that could be accessed directly using sc_include_library or reference them by accessing $this->Ini-><property>. There’s any way to do that?
Example: My idea is to create the next tags:
<img src="<?$this->Ini[‘public_lib’]/images/myimage.png">
Many thanks,

Dani

[SOLVED] You must include the file to use in the app in the Application -> Settings image section, then the attached image file is uploaded an you can acces via

 <?=$this->Ini['public_lib'] ."/images/myimage.png"?>

If don’t do this, then the file is not accessible.
