Jquery, Highcharts enable html exportChart

Question

I have some chart with legend

legend: {
        useHTML: true,
        labelFormatter: function () {
            return '<img src="linkToPicture"><br>';

            //return this.name.replace(/\d+/g, '');
        }
    }

How can I save it with standart highchart functions? Problem is that HighCHart export saves text but not pictures, what is a reason of problem? P.S. Actually legend looks fine in browser, problem is with exporting chart. Thanks

Answer 1

The problem is that the export function of Highcharts connects to their server, so without an internet connection the export function will not work. Therefore I think the function works like this: it sends the data to the server and the server generates the img or pdf and sends back the file for us to save. So, your image will not be sent to the server to be exported, only the text.
