Hi,

I am creating a method that returns html for a picture element, but gets the below error.

My code is:

public static string PictureHtml(string[] srcsets, IPublishedContent image, string classAttr)
{
    string output = "";
    int i = 1;

    foreach (var srcset in srcsets)
    {
        string[] srcsetAttributes = srcset.Split('|');
        if(i != srcsets.Count())
        {
            output += "<srcset src=\"" + image.GetCropUrl(200, 200) + "\" />";
        } else {
            output += "<img src=\"" + image.GetCropUrl(200, 200) + "\" alt=\"" + image.Name + "\" />";
        }
        i++;
    }

    return "<picture class=\"" + classAttr + "\">" + output + "</picture>";
}

Code isn´t finished yet and therefore GetCropUrl parameters are hardcoded to 200.
