If you are in the "Manage Attachment" window, you will see the first box is labeled "Upload file from your computer". Click on the "Browse" button and navigate to your photo file and select it. You can do this up to four times. When finished click the upload button and wait while the photo(s) are uploaded to this site. When the photo(s) are uploaded, they will be listed below the URL box with your total size labeled "Current Attachments". You can then close the window and your photo(s) are attached to your post and can be viewed in the "Preview Post" view and will appear as part of your post in the thread.
If you use the paper clip method, you can insert the photo within the body of your text for clarity of explanation, but it is more steps when attaching multiple photos.
