Making a variable global?

[Merriweather]

I installed a the VB Image Hosting mod (https://vborg.vbsupport.ru/showthread.php?t=123481) which I love, but have an issue and though it's marked "supported", the author is not replying. I am hoping someone can help.

There's a template modification made to make the number of images the user has uploaded show in the postbit. It works fine in the forums, however, if I post an announcement, that space is left blank, like it can't retrieve the variable to know what to display.

The variable it pulls into the postbit is called $post[vbimghost] and I'm wondering if someone could help direct me as to where to find what that variable is pulling from? I've gone through the files from the product but there's no "$post[vbimghost]" in them, so I'm a little lsot as to where to look.

I'm newer to vB, but not to programming, so a push in the right direction would be helpful.
