C4:W3:Lab2: How to test on our own image?

I just finished with the U-Net lab and I wondered how do we test our model on dev set and test set and also the final evaluation of our model was done by picking images from the dataset meaning that we are just checking the accuracy on the dataset i.e. train set. How can we test it on our own images?

In the forlder where the test images are, you can place your own images. Make sure if needed to resize them, if the preprocessing of model does not do it!
