Hardcoded content dir in plugin's code

This plugin does not work if I have renamed my wp-content and uploads folders to something other than their default names. I looked through the source code and it is referencing the wp-content directory directly without using WordPress coding standards in this regard. More on how to fix this.

It returns something like Uploads folder named “slideshow-gallery” cannot be created inside “wp-content/uploads/”

It would be great if this could be fixed.
