From one Sophie lover to another...
When you want to post a photo as an attachment to your post:
Hit post or reply then scroll down the page to additional options section and hit manage attachments. Then hit browse and choose your photo from your my pictures in your computer. Photos need to be saved as jpeg or gif file. The file can be no larger than 200KB for jpeg and 150 KB for gif files. Digital camera photos are larger so you may want to use a free program like photoscape or there are other programs available. If you go to Forums then Yorkie Photos there is a sticky that explains it probably better than I. You're not a dummy, it took me awhile to get it, too! Good Luck
