I am using Orange data mining in order to create a facial recognition workflow with some prototype widgets. To do this, I am trying to import some images (test data) using the import widget.

My question is: which file format do I need to use in order for the image data to be compatible with the import widget? In other words, which file format should I use to upload the image?

I have tried using JPEG but when I click "browse for images" to search for images on my desktop, it doesn't allow me to select anything to import.

Does this imply that it is not compatible? Is there a specific file format that I should be using in order to do the image detection/embedding process?

    $\begingroup$ When I try this, I select a folder, not individual images. For me, jpeg then works... $\endgroup$

As r.kfr said: Import Images works with folders, not individual images. Place all images in a folder and select it for import. Note that if you have images in different folders, Orange will consider each folder name as a class label for images.

Alternatively, you can create an Excel/CSV file and define the path to the image. Mark it with meta type=image in the third header row. Here is how to define the header.


First add the File widget, then create a xls file with 2 columns:

  1. name of image
  2. image path

Orange will import the images by itself.
