Can invisalign extend my teeth more front and widen my jaw? (photo)

Based on your photo, I would caution against appliances to expand your upper and lower arches (jaws).  Doing so can change the way your mouth feels significantly.  You may speak differently (e.g., with a lisp or slur).  I would definitely consider veneers.  They are fast and will do exactly what you need them to do.  You will not have to worry about relapse and if done by an excellent cosmetic dentist, you should expect them to last at least 20 years with proper dental hygiene.  In my office, I'm so confident of the longevity of the veneers I place, that I put a 10 year warranty on them.  The best advice I can give, is to research some cosmetic dentists, and review their before and after pictures thoroughly to make sure that they can give you the results you're looking for.  I hope this helps.

More photos are needed to give you a better answer. Invisalign can broaden your smile somewhat but it is limited. Every case is different. Some cases are better suited for braces. invisalign.com or damonbraces.com have smile galleries to look at. I recommend visiting an orthodontist to help you achieve you are looking for!
