Hi,
first thanks for the superb product.
I'm having a little issue with the custom images for some videos.
The images work fine in the gallery mode as thumbnails, but when I select a video for playing some of the images don't then show up as enlarged on the video screen - but some do.
I can't seem to work out why this is.

For example, in the below link:
www.bikerman.co.uk/index.php/superstition/videos/documentaries
If you click on the 'Mea Culpa' video the custom image shows OK on the next screen.
If you click on the 'Expelled' video it doesn't.

Kindly try using absolute URLs for images instead of the relative paths.
