    var context = BrowsingContext.New(config);
    var document = await context.OpenAsync(url);
    await document.WaitUntilAvailable(ct); // Wait for page loading
    var imageLinks = document
        .QuerySelectorAll(".content-inner p a")
        .OfType<IHtmlAnchorElement>()
        .Select(x => x.Href)
