I have an problem with the thumbnail Facebook is showing, when I send an link to my web side to someone on Facebook.
Facebook is showing a thumbnail picture from a password protected folder.
Is there a way to change this, so I can choose which image Facebook Is using as thumbnail ?
I am currently using version 2.8.4

That is assumedly because the first folder Imagevue finds in your gallery, happens to be a passworded folder. You can manually edit the default Facebook share picture though ... Open the file
iv-includes/templates/default/index.gallery.phtml, line 23:
<meta property="og:image" content="<?php echo pageURL().htmlspecialchars($this->firstImage->thumbnail); ?>?<?php echo htmlspecialchars($this->firstImage->getThumbnailMTime()); ?>" />
... change to ...
<meta property="og:image" content="http://domain/path/file.jpg" />
Simply add an absolute path to the image on your web server. It does not have to be a thumbnail, in fact its better if its not because Facebook recommends minimum 200 px width/height.

After you changed the code and refreshed your page, go here add your gallery link and check the result:

Normally, you need to force Facebook to empty its cache also ...

I tried the Facebook debugger. It fetches the right link in the code but it says the image is to small and is going to use another thumb instead. The image is 1000px wide! How do I force Facebook to refresh its cache?
EDIT : Works now! Don't know how it refreshed... Well... Thanks!
