            int height = 0;
            for (Element src : media) {
                if (src.tagName().equals("img")) {
                    try {
                        width = Integer.parseInt(src.attr("width"));
                        height = Integer.parseInt(src.attr("height"));
                    } catch (NumberFormatException ex) {
                    }
                    if ((width > 249) && (height > 249)) {
                        System.out.println("Path:  " + src.attr("abs:src")
                                + "\n wd " + src.attr("width") + " hi " + src.attr("height"));

                    }

            }
        } catch (org.jsoup.UnsupportedMimeTypeException e) {
            System.out.println("Exception " + e);

        } catch (IOException e) {
            System.out.println("Exception " + e);

In the given url https://i.stack.imgur.com/MgQWo.jpg, no <img> contains width and height attributes.

So width and height always equal 0, if ((width > 249) && (height > 249)) is always false, no image is found.

If you just want to get the src to the main image, rather than looking for a specific size (given that they're not setting one), you can make a CSS like div.image img. This looks for <div class="image"><img ...>, which matches their maing image.

You also don't need all that loop code.

Document doc = Jsoup.get(url).timeout(t).get();
Element image = doc.select("div.image img").first();
String source = image.attr("abs:src");
