First you need a picture in your computer somewhere. Then it needs to be resized to under 100kb. You should have some sort of photo editing software where you can do this on your computer or ms paint might work.Then you click on Embed pic in post at the bottom of page, and click here to upload. Then find the picture in your computers memory and double click on it.

Or you can use www.photobucket.com and upload your pics there. I am not a photobucket expert, so maybe someone else can help you out there.

Hope this helps and makes some sense to you.
