Well finally, i tested vbgallery with the beta3
First.. i don't like the class programming of vb4...
comparing vbulletin only pages
+10 queries per page.. and + 30% memory usage.. but its a beta.. so we will see..
As to vbgallery...
Install went flawlessly... (that's good news..)
Only 1 image (rating) it couldn't find.. but that will be an easy fix..
Then to the functionality...
That's a bummer...
eval fetch_template doesnt exist anymore.. (well it does but triggers an error giving a warning at each call..)
(the good thing is that the warnings are triggered by vbulletin, they added :
Code:
Content visible to verified customers only.
So that's not bad for debugging...
Actually, without a new version, gallery is unusable
as is for vb4.
At first sight.. it needs..
- a complete rewrite of gallery_global.php
- Small rewrites of functions_gallery
- a partial rewrite of the 10 main files (replacing fetch_template with $templater = vB_Template::create(...
- a complete rewrite of the templates (Thats the BIG part)
Its not that hard.. but, it will be very time intense.
(and here is my suggestion)
So Michael, forget about dating, girls, food, drinks and holidays 
Its going to be lots of work! 
More seriously, i think it is feasible, and will work nicely..
But I suggest you don't upgrade to vb4 if you are in production environment
