No need to apologize. I've never used the .nomedia method either. But this is how I'd do it.
First download a file explorer from the market. You can find one by searching for "file explorer" in the market. Astro is a popular one, but I use Root Explorer since I'm rooted. Either way, once you have it, open it up and go to sd card. When you're there, with either one you get, hit the menu button on the phone and create a new folder. Then name it ".nomedia". Your folder is now created. Then transfer the pictures you want to hide there.
Your pictures are located in sd\DCIM\Camera. Again use the file explorer to find that folder. When you're at those pictures, theres usually a multi select option so you can select more than one. It would be in the menu option. Select the pictures and then move them. Then go to the .nomedia folder and paste them. Also long pressing a single picture should bring up those options too.
If you have any problems, let me know what file explorer app you installed. I'll download that app and walk you through the options, as long as it's free.
As far as I know, you'll have to do this every time you take a picture you want to hide. Unless someone else knows an easier way.
