Youtube doesn't accept jpegs as a recognised format. (If you want to create a Youtube file with a single picture you have to use Windows Movie Maker - or similar- to create a video with a static image, and then upload that).
AB doesn't recognise jpegs either. The way to show us a picture is to upload it to an image-hosting website and then post a link to it here. Tinypic is frequently used for that purposes, as no registration is required:

(Use the 'direct link for layouts').
