# Image fields and signature extraction

> Use image field types in Affinda to extract logos, signatures, photos, and other visual elements as cropped images alongside text data from documents.

Affinda models can identify Signatures, Headshots, and Seals in your document using our image detector. Within the API, we will return a url of the image extracted from the document. The presence of this url can be used to signal that the particular image type exists on the document, or the image can be downloaded and added to your system.

<Card title="Signature">
  Returns the image of the signature. The presence of the parsed value can be used to verify that a document contains a signature.
</Card>

<Card title="Headshot">
  Returns the image of the headshot or person.
</Card>

<Card title="Seal of Authenticity">
  Returns the image of the seal of authenticity. The presence of the parsed value can be used to verify that a document contains a seal of authenticity.
</Card>

<Warning>
  ### When adding images as a new field, existing documents will need to be reparsed for the model to identify the image on the document.
</Warning>

<Note>
  For extraction of other image types, [please contact Affinda to learn more.](https://www.affinda.com/contact)
