HI, @pamelafox. I cannot reproduce the issue with the fiddle you provided (tries to get an old version of Highcharts from a URL that does not exist). However: the same JS works just fine with a more recent Highcharts version: http://jsfiddle.net/ZZ7Kd/304/. Hope this helps :)

Ah, sorry, I had fixed the JS include in my own version. What I mean is that the images do not render when piped through the server. Here's the server code:
var chartOptions = {
chart: {
renderTo: 'container',
marginRight: 80,
type: 'spline'
},
xAxis: [{
tickWidth: 0,
lineWidth: 0,
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
}],
series: [
{
data: [
{ y: 29.9 },
{ y: 71.5 },
{ y: 106.4 },
{ y: 129.2 },
{ y: 144.0 },
{ y: 176.0 },
{ y: 135.6 },
{ y: 148.5 },
{ y: 216.4 },
{ y: 194.1 },
{ y: 95.6 },
{ y: 54.4 }
]
},
{
data: [
{ y: 220, marker: { symbol: 'url(http://www.highcharts.com/demo/gfx/sun.png)' }},
{ y: 220, marker: { symbol: 'url(http://www.highcharts.com/demo/gfx/sun.png)' }},
{ y: 220, marker: { symbol: 'url(http://www.highcharts.com/demo/gfx/sun.png)' }},
{ y: 220, marker: { symbol: 'url(http://www.highcharts.com/demo/gfx/snow.png)' }},
{ y: 220, marker: { symbol: 'url(http://www.highcharts.com/demo/gfx/sun.png)' }},
{ y: 220, marker: { symbol: 'url(http://www.highcharts.com/demo/gfx/sun.png)' }},
{ y: 220, marker: { symbol: 'url(http://www.highcharts.com/demo/gfx/sun.png)' }},
{ y: 220, marker: { symbol: 'url(http://www.highcharts.com/demo/gfx/snow.png)' }},
{ y: 220, marker: { symbol: 'url(http://www.highcharts.com/demo/gfx/sun.png)' }},
{ y: 220, marker: { symbol: 'url(http://www.highcharts.com/demo/gfx/sun.png)' }},
{ y: 220, marker: { symbol: 'url(http://www.highcharts.com/demo/gfx/sun.png)' }},
{ y: 220, marker: { symbol: 'url(http://www.highcharts.com/demo/gfx/sun.png)' }}
],
type: 'scatter'
}
]
};
var exportSettings = {
'type': 'png',
options: chartOptions
};
Highcharts.initPool({maxWorkers: 2});
Highcharts.export(exportSettings, function(err, res) {
Highcharts.killPool();
if (res) {
resolve(res.data);
} else {
reject(new Error(err));
}
});

Yes, it seems that the export server prematurely renders an image of the chart when producing an SVG from a Highcharts config. Exporting a chart via the export menu sends the chart SVG and not the config to the server, which seems to work fine.

Also looking for a way to do this.

@cvasseng with the old PhantomJS script we looked for references to online image files in the source, downloaded them first, then returned the snapshot once all image files were loaded.

For me it doesn't work to render images in callback as well.
This my callback
function(chart) { chart.renderer.image('https://www.highcharts.com/samples/graphics/sun.png', 100, 100, 30, 30).add(); }
which I call like this
highcharts-export-server --infile /home/highChartsExportImages/0/1439-1000.js --callback ...Resources/js/logoCallback.js --type pdf --outfile /home/highChartsExportImages/0/1439.pdf

Facing the same issue. Such as for the following JSON data structure,
"series":[{"data":[{"y":0.06,"x":3.5815,"marker":{"symbol":"url(https://www.highcharts.com/samples/graphics/sun.png)","width":40,"height":40}}}]
The rendering is inconsistent in the sense that it loads at times and doesn't at others. I am assuming the highchart export server returns the graph much before the images from the URL are loaded onto it.
Alternatively, is there any other way to load images as markers onto the graph by passing such a parameter in the JSON file?

Commit cf04c66 implements a wait poll that waits for images to finish loading. It will timeout if the images aren't loaded within 2 seconds.

@cvasseng Can you please, reopen this? I'm facing the same issue - the SVGs used in markers are loaded like 2 times out of 10:
"series": [
{
"type": "line",
"lineWidth": 0,
"data": [
{
"x": 1592586000000,
"y": 86,
"marker": {
"symbol": "url(https://dots.dataontouchdev.com/images/weather/yr_weather_symbols/svg/01d.svg)",
"width": 40,
"height": 40
}
},
...
