Can I add an image to the signature field?

Además de eso tengo otra pregunta: ¿es posible añadir la firma pero con una imagen?

Hi cimeiformularios,

Thanks for reaching out to Jotform Support. Unfortunately, our Spanish Support agents are busy helping other Jotform users at the moment. I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Spanish, let us know and we can have them do that. But, keep in mind that you'd have to wait until they're available again.

Now, let me help you with your question. Unfortunately, It's not currently possible to add an image on a Signature field but you can add a separate Image element field on your form. Let me show you how:

1. On the left side of the page, click on Create Form.
2. Click on the Add Form Element menu on the left side of the page.
3. Under the Basic tab, scroll down the list and choose the Image element

Give it a try and let us know how it goes.
