Hi Audrey,
The best way to insert an image into a post is to use the image icon that appears in the text editor. It is the one that depicts a mountain inside of a frame and from there it will ask you to upload an image that you would pick from your own computer by clicking the pinkish Upload Image button and selecting the right image. Then once you have you can insert it right into your reply. Then from there you can drag to resize. You would want to make sure you are clicking Upload Photo and then selecting a photo from your computer in the steps. I hope that helps.
