Hello and welcome from 35 miles north of Gettysburg! @CMWinkler has given sage advice on uploading a photo (file), try again using the "Upload a File" button at bottom right of the posting area as he mentioned. Then, just select the photo from your hard-drive you wish to upload, click it and (VIOLA!!!! ) there's your photo embedded into your post. Remember to click the "Full Image" option once the photo loads into your post. Looking forward to your what is it photo.
