Is there a maximum limit to image folders.

I have Serviio working on my Raspbbery Pi using a small test image folder, images are showing on the tv with thumbnails. I have changed the image folder to another folder with hundreds of folders and images, no images are appearing and refreshes don't show anything. I've checked paths are correct, Is there a limit to the number of folders it can handle.

no limit. It might take some time to start appearing, assuming the RPi is slow and it has to resize the images for thumbnails, etc
