[How to: place pictures side-by-side?]

I am very sorry for not having a correct title, I thought it was sufficient. I am very new to Paint.net and I am not that computer smart in the first place so many of the topics that I found when I used the search tool (I did before I posted my question) were way over my head. I have tried using the layers and cant seem to get the hang of it. I cant get them to be side by side they always end up on top of each other. Sorry if I am not smart enough for this site.

[How to: place pictures side-by-side?]

I am trying to take severyal pictures and crop them then put them side by side (not layered one on top of the other) to make one single picture. If anyone can please tell me an easy way to do that. If its not too hard I would love to have a border around them and a little text. Thank you in advance to anyone who can help.
