Hello,
Sorry you've had a bad experience with this. It should be possible to upload the cropped image to the database, you just have to run the action "Upload Cropped Image ImageCropper A". Please reach out on the forum if you need help using the plugin properly or are experiencing bugs. https://forum.bubble.io/t/image-cropper-new-plugin/58182
I know it's not the simplest setup, but I've set this up to allow for maximum flexibility. This makes for a more complex setup, but allows the most usability (plugin author)
