At the top of your post where it allows you to do bold, font size, etc there is an image for inserting an image. Its the 3rd image from the right. Left click on it. A box will pop up that says insert image. Under Insert image you will see "From computer" or From URL. Click on the tab "From computer". At the bottom middle you will see select files. Left click on select files. Actually for some reason I can't get it to pop up. To the Right of selct files it says basic uploader. Click on that. Then click choose file and browse to your picture(s) you want to upload.
