Adding photo Gallery?

Can someone list the steps for me in setting up a photo gallery here on Pnet? They ask for location? They ask for description? Very computer challenged, sorry.

just name the gallery…
Location and description are optional.

You may have to resize your pics to fit.

Thanks, I get it now!
