There was a button on the right, so I’m going to click it.  When I mouseover, it says Add NextGEN Gallery.  Ok, that didn’t seem to help as it expects me to already have a Gallery ready to insert.  Next, I’ll try the first button after “Add media:”  That seemed to work.  I selected about 12 to 14 images and it started uploading them one at a time.  I did get an HTTP ERROR at some point during the process.  I don’t know why.  That’s all it said.  I guess if I noticed some images missing, I’d just re-add them probably.

I clicked the “Save All Changes” button, even though I didn’t really do anything else.  After that, it gave me an option about some ordering of the images, how many per row or column or something.  Then I just clicked Insert Gallery button.

I’m back in the Editor again now after taking a look.  That does look pretty good!  Doesn’t it?

I noticed a “Gallery” button in my menu near the bottom.  I’m going to click that next and see what other options it may have.

Update:  Ah, that was for the NextGEN gallery plugin that I apparently didn’t end up using at all.  I found out what my HTTP ERROR was from.  I ran out of my alloted disk space of 10MB with the images I uploaded.  That makes sense.  It might be better to add images hosted remotely so you don’t run out of space.  You can do that on the same menu but use “From URL” instead of “From Computer” when adding the pics.  Not as awesomely easy but keeps you from running out of space.  I added a jQuery lightbox plugin so that my gallery uses a cool effect when viewing an image.
