Value of
<input type="">
What does <input type="image"> do?
Defines an image that is clicked to submit a form.

Code Example

<form action="myform.cgi">
<input type="file" name="fileupload" value="fileupload" id="fileupload">
<label for="fileupload"> Select a file to upload</label>
<br><input type="image" src="/wp-content/uploads/sendform.png" alt="Submit" width="100">

The image value allows us to specify an image that is used to submit a form, in place of a Submit button. Even though this image is being used as a button, you must still specify an alt description for the image.
