Thumbnail image preview fails to display after preloading an image in dropzonejs

Currently, I have a form where users can input their name and upload an image (logo). The client side language being used is AngularJS with dropzonejs as the image upload library. When the user clicks on the 'Edit' button, I want them to see a preview of the image they uploaded previously. To achieve this, I referred to a solution posted on this thread. However, I encountered a problem where if I upload a new image after preloading the initial image, the preview of the new image does not show up. Below is the code snippet for preloading the initial image (an angular directive is used for this purpose):

if(scope.initialFileAddress != null && scope.initialFileAddress != "") {
      mockFile = {name: scope.initialFileName, size: 1000, type: "image/jpeg"}
      this.addFile.call(this, mockFile)
      this.options.thumbnail.call(this, mockFile, scope.initialFileAddress)
}

Answer №1

The issue was identified in the following line of code:

this.addFile.call(this, mockFile)

It should be replaced with:

this.options.addedfile.call(this, mockFile)

By making this adjustment, the image will not be included in the main list of files to be uploaded. This modification successfully resolved the problem in my particular scenario!
