Although a photo hosting site will work, you really do not need to do that. Take a photo, reduce the size if it is over 1mb, then place it on your desk top. Click on Reply to thread, or quick quote or however you do it to post on a thread. Then scroll down below the screen you are typing on. You will see a option to "Manage Attachments". Click on it. Then a pop up will appear. In that pop up, it wants you to put in a location of your photo. Since yours is on you desk top, hit the "browse" button next to the option of "upload from your computer". After that pop up appears, pick "desktop", look for your photo, click on it and then click "open". The address for the upload will then appear in the first pop up box, then you click "upload", it's next to that browse button mentioned above. You are then good to go. After you hit upload, you may or may not see the photo address in the text of the thread, so go below where you were writing your thread and hit "preview post". The photo you uploaded should show up and you are good to go. (Then hit submit reply if you liked the preview).....good luck and be safe.
