Uploading Assets to Buckets via external Form

Is there a way to have an external form on like the contact page and have an image upload field and that go into a specified bucket in my assets?

Ok, cool, if I could just learn how to work these add-ons! LOL

Is there something built to do something similar to how the members/profile.php form works?

Where the form on that page can update the info say in a region?
