  1. Add a file upload question to your step.
  2. Enable Show image preview. A new option to enable annotation appears. File upload question image preview and annotation options
  3. Enable Annotate image.

Annotating images

When annotating images, it’s important to understand how the files are saved. When you upload an image and start drawing on it, the original image file and the drawing are saved separately, temporarily. You can save the form and reopen it, and still have the option to continue annotating or remove all annotations and keep the original image file. Once the step is submitted, the two files are merged, meaning the original image file is overwritten and there is no way to undo the annotation.
