Thanks. I made a bunch of guesses how to proceed. 
I'm sure I erred, but here's what I did.
What should I correct by way of use model?

I'm not sure what the next step is (either rpm -ivh or rpm -Uvh)
$ sudo rpm -ivh libmtp-1.1.6-0.el6.x86_64.rpm
==> Preparing... ########################################### [100%]
==> 1:libmtp ############################################## [100%]

I'm not sure how to check if it worked or not, so I'll just re-run this and compare output:
$ sudo yum install libmtp
==> Package matching libmtp-1.0.1-2.el6.x86_64 already installed

Hmmm... I had expected a later version, and, at the same time, I would have expected the same wording. Neither occurred.
It says it's the same version; but it uses different wording to do that.
But I don't see any errors either, so I'll move to the next step.

Hmm... What is the next step?
I guess the next step is to plug in the Samsung Galaxy S3 via USB cable and see what happens.

Drat.

I unplug the USB cable, and plug the USB cable back in:
On the desktop, a new entry called 'disk' shows up:
Places->disk
When I click it, I see what "appears" to be the phone.
Clicking again (to take a screenshot) I now see a newer entry below 'disk' called 'SAMSUNG_Android_SGH-T999'.

Clicking on SAMSUNG_Android_SGH-T999 in the file browser, shows what "appears" to be the phone (except that all folders show up as empty).

It looks like the libmtp RPM worked but I'm not sure of the use model to access the picture data on the cellphone (or any data on the cellphone, as all directories show as empty when I click on them in Centos).
