appreciate your follow up — i am running 5.3.6 and have been having this problem. I will attempt to upgrade PHP and see if it works for me. cheers!
I’m in the same boat!! This plug-in is terrific!
I’m having the same issue — and i’m trying to access the Image-URL via ‘meta:’ in a post-based slider. My workaround is create a custom field text type that cntains the URL text of the image — but I’d really like to use the wysiwyg image controls.
Accessing it via the Meta tags only returns the image ID.
Did you figure this one out?
