Is SMF Gallery Pro SSI still required?

[landyvlad]

I've had SMF Gallery Pro installed for quite a while (since 2015 I think?) Anyway back in the day when I installed it I also had to install a mod called "SMF Gallery Pro SSI"

I can't even recall what it did...except that I needed it at the time.
Is that still a thing?
If so when is it needed?
And if I do need it, where do I find it?

I've just renewed my licence, and will be installing Gallery Pro 9.0b

I just found this but it;s still not clear to me:
a) what it does
b) If I need it
c) Why it isn't included in the core product, rather than an add on?

Not needed for most people. It adds functions to SSI.php which allow you to call SMF Gallery PHP functions for use in your own scripts.
