| Name | Type | Description | Defaults to |
|---|---|---|---|
| ngModel (required) | string |
Assignable angular expression to data-bind to. The data URL encoded image data will be available on the src property. If the angular expression is a string, it will be assumed to be an URL path to an image. The path will then be converted to an object with the path available on the src property and with the isPath property set to true. |

| accept | string |
Works similarly to the HTML specification to restrict the input to certain mime types. Sets image validation error key if the user selected file does not match. NB: File extensions are currently not supported. |
image/jpeg,image/png |
| dimensions | expression |
If this expression is evaluated to be false (or falsy) the $error.dimensions property will be set and the image will be considered invalid. The image's dimensions are available as height and width. |
