Slim Image Cropper

The Slim Image Cropper for Gravity Forms plugin has been discontinued by the original developer. Image Hopper is the recommended replacement and has many of the same features, plus additional capabilities. However, Image Hopper doesn’t have 100% feature parity with Slim Image Cropper.

Feature Parity

These features are supported by both Slim Image Cropper and Image Hopper:

  • Responsive and beautifully animated
  • Correctly handles device orientation
  • Very fast
  • Easy to Configure
  • High Quality User Experience
  • Drag and Drop
  • Resize images automatically
  • User can adjust the crop and rotation (requires Image Hopper Editor to be enabled)
  • Define max file upload size
  • Define JPEG compression ratio
  • Define required input image type
  • Customize output image size
  • Supports touch interaction on mobile devices
  • Validate images before upload
  • Multiple fields per form
  • Post Image field type
  • Minimum image dimensions
  • Image quality warning (like the minimum image dimensions, but still allows the image to be uploaded)

Not Supported

These features are supported by Slim Image Cropper but not by Image Hopper:

  • Set image ratio — you can set the image size with the Crop to Dimensions option enabled to achieve similar results
  • Force output format (either JPEG or PNG)

New Features

These features are supported by Image Hopper but not by Slim Image Cropper:

  • Upload multiple images to the same upload field (you are not limited to one image per field) and then reorder those images
  • Attach uploaded images to Notification emails
  • Support for .webp and .heic (converted to .jpeg) images
  • Deep integration with the Gravity Forms ecosystem, including native support for popular add-ons like Gravity PDF, GravityView, Gravity Flow, Gravity Perks Nested Forms, Gravity Perks Media Library, Gravity Forms User Registration, Gravity Forms Advanced Post Creation, Gravity Forms + Custom Post Types, and the WooCommerce Gravity Forms add-on.
  • Intuitive Settings — Image Hopper takes a convention over configuration approach to using the plugin, meaning it is easier to setup and configure.

Migrate from Slim Image Cropper

These are the steps you should take after you deactivate Slim Image Cropper and install and activate Image Hopper:

  1. In your admin area, navigate to the Gravity Forms editor for a form that contains a Slim Image Cropper field
  2. Add a new Image Hopper field below each of your Slim Image Cropper fields, and configure accordingly. Because Image Hopper can support multiple images per field, you may be able to consolidate multiple Slim Image Cropper fields.
  3. Leave your existing Slim Image Cropper fields in the form (Image Hopper automatically hides the Slim and Slim Post fields from your end user, but still displays the images in your admin area).
  4. Save your Gravity Form
  5. Test that you can now upload images using Image Hopper and that you don’t see the Slim Image Cropper fields while filling out the form.
  6. Verify you can see the Image Hopper images on the Entry Details page for your newly-submitted test entry
  7. Verify that you can still see the Slim Image Cropper images on the Entry Details page for older entries
  8. Repeat steps 1-7 for each of your Gravity Forms
