folder with images is deleted when create a .skl file

I want to keep two folders with different images and use one of the groups inside my script depending on the browser I use to run the test (browser name passed by parameter).

It works OK when I run the test from the IDE, but when I create a .skl executable file, the folders are deleted. Is there any way to keep these folders into the .skl file?

Thank yo very much! Regards,

Fabián.
