How a Image Dimensions Checker finding reads
Input
Example for Image Dimensions Checker. Take a realistic input you could defend in a review. Choose a file or switch to the URL field and paste an image address. The result should reflect that input. Width and height come from the loaded image, in pixels. If a second field is empty, leave it empty on purpose and read what the output omits. Wait for the image to load in the page.
What you should see
Then change one thing and run it again. Read width, height, and the aspect ratio. The new result should move with that change. If it does not, you are looking at a control that is only a label, and the guide above is the place that says so. Width and height reduced to the smallest whole-number ratio.
