Thanks for getting back so quickly.

I tried what you suggested and it helped to some extent.
It works as long as I copy and paste the link directly to share on facebook.

Both problems persist when I use the 'f' button on the gallery's button bar to share. The files are still cached somewhere but I can't figure where. Right now, all I can think of is to disable the button bar.

I also have another issue with the button bar - it never completely aligns to the center of the image. My pet peeve.

I have a couple of issues with my juicebox builder pro:

1) Image display when sharing gallery:
The graph tags are set to use a particular image when the gallery is shared on facebook. (og:image)
But a different picture from the gallery loads in the snippet. And when the link is posted despite this, the final picture displayed is a completely different one!
The image I want to share is never the image that is finally shared. It just chooses one of 2 images that it randomly seems to have selected on its own.

2) Issue with description of the gallery:
Under 'lite' I set the Gallery title and under 'general' I set the gallery description.
In spite of this, every time I try to use the button bar to share, it says 'Juicebox gallery' in the description for some images!!

I tried clearing the cache and switching browsers but this doesn't change anything.

Can you help me fix this bug?
