    That's just a thumbnail preview of the uploaded image so it is expected to be small. However, it is scaled properly once it is sent to your email as well as on the form submissions page. You can also download the image to get a good view of its actual dimensions.

    Anyway, it is still possible to scale up the preview image on edit mode, just inject this CSS codes to your form and all preview image in edit mode will have a minimum 200px dimensions.

    div[id^="clip_"] img, div[id^="clip_"] {

        min-width: 200px;

        height: auto !important;
