If you ask a quetion in Community, the only way to add photos, etc. is by answering your own question. Post the question, then click on 'reply' as usual. Then put in something like "here is the link" or "here is the photo". You will see tabs under your answer for photo, link, and video. If you click on the 'photo' tab, it will allow you to search your files for the photo you want to upload. If you click on 'link', it will allow you to easily add a link.
