Steps:

1. First create an entity in your domain model say "TempUpload" and set generalization to System/Images or System/Files.

2. Add a dataview container to your page and set data source as a new Microflow. Create a new microflow which must do must do two things:

        1) Create an object of entity "TempUpload"

        2) Return the newly created object at the end of microflow

3. Add 2 columns in your data container using layout widget. On the left add the File or Image Uploader widget and on the right column add a List view container. Add a heading above the list as "Uploaded Files/Images".

4. Set the data source of the List container as entity "TempUpload".  Add a dynamic image widget inside the list. Set the image source to "TempUpload". Set height and width to 100px each (Optional). Now this list will display all the newly uploaded files/images.

5. Below the file/image uploader widget on the left, add a save object button. We will add custom save logic. Set the onclick action of the button to a new microflow. Create a new microflow that will do the following:

         1) Commit the "TempUpload" object

         2) Show the current page.

         3) show a message "Image Uploaded successfully".

We are again showing/loading the current page because it will again create a new object for next image.

This is how you can upload images and simultaneously show the newly uploaded images as a list.

If you already uploaded the image using the standard Mendix image upload widget and you just want to show the image that has been uploaded, place a dataview on the page to retrieve the image and then use the standard dynamic image widget from Mendix (see images below). If needed, you can add a refresh of the parent object to make it immediately visible on the page.
