Why I had to draw my signature instead of uploading a photo of that!!!!!!?

In your contract there is a field that any body had to draw there signature with mous!
can u imagin how hard it would be!
why I can not upload a photo of that!!

You are free to choose whether you want to add an E-signature widget or just use an Upload Field for getting signatures of the users.  I would suggest you create your account first in JotForm if you haven't signed up yet. 

After you have created your account, you can now start creating your forms. Please see this guide: How to create your first web form.

If you need further assistance, please let us know.
