Working on this for a client and have found this:
I’ve tracked down what seems to be the issue with the images not showing but don’t know how to correct it.
Seems to be when OnSwipe passes the image URL to thumbs.php
This works:
https://www.domainname.com/wp-content/plugins/onswipe/framework/thumb/thumb.php?src=/wp-content/uploads/2011/04/dino.jpg&w=430&h=250&zc=1&q=75&fx=0
This does not:
https://www.domainname.com/wp-content/plugins/onswipe/framework/thumb/thumb.php?src=https://www.domainname.com/wp-content/uploads/2011/04/dino.jpg&w=430&h=250&zc=1&q=75&fx=0
The difference being, OnSwipe is passing “https://www.domainname.com” to thumbs.php
I’ve emailed support but have not heard back if they know a quick fix.
