How do I upload a picture from my harddrive into a text box form field?

I am trying to upload an image from my hard-drive to text feature in a form > but it is only giving me an option to insert the source? Which I presume means a link? 

The image is on my harddrive. 

Thank you!

If you want to upload an image, you can use the Image in the Basic Fields. See the image below:

For text field, you need to add the Image link or URL. You can upload it to any image upload site and get the link to paste it in the Source. 

Hope that helps. Let us know if you need further assistance. Thank you.
