Photo Gallery - Recommendations

[Pasci]

Hello,

We are in the midst of creating a brand new massive corporate website run by typo3.
For this website, we will also have a section for a photo gallery.

My question to you is, should we
a) embed an external open source photo gallery such as mentalo gallery or coppermine, etc
OR
b) use a typo3 photo gallery extension

If you recommend option b, please tell me why, and most importantly, which typo3 photo gallery extension would you recommend?

Thank you in advance.

Best Regards,
Pasci

Alright...

I opted for the chgallery.
It's easy to implement, has lightbox and directory support, and validates.

Cheers,
Pasci
