Made the following changes highlighted in red boxes to support using this node in Linux OS's. Simple fix since module already imports the os module.

Don't forget to delete node's cached python import files for change to take effect. These files are in custom_nodes/ComfyUI_Comfyroll_CustomerNodes/pycache/ folder. Delete the cache files then restart Comfyui and node should work in Linux.

Also using "os.path.join()" is another way to fix this issue.
