Non user image & data submission form

I am interested in having a form that excepts images and other normal text fields.

For example:
A user will fill a form about him/herself and attach a photo and click the submit button. The user need not to be logged in to do it.

I have been Googling since morning but didn’t came across only similar questions posted some time ago.

Is this possible, I don’t mind learning to write a plugging for that. How to achieve this. Thanks in advance.
