ExtentReports - screenshot not in the report - broken image

I'm trying to add a screenshot to my ExtentReport HTML file, but for some reason, the image is not there even though it DOES exist and the console shows that it's looking at the correct place (href is correct).

This is the latest trial code:

Screenshot screenshot = new AShot().shootingStrategy(ShootingStrategies.viewportPasting(1000)).takeScreenshot(driver);
String destination = getScreenshotPath();
ImageIO.write(screenshot.getImage(), "IMG", new File(destination));
test.fail("Details: " + test.addScreenCaptureFromPath(destination));

The screenshot gets saved in the destination. When I try the debugging mode, or look at the report, it's printed as:

Details: com.aventstack.extentreports.ExtentTest@62041567 and there's a broken image under it:

As suggested - the absolute path could be a solution, but I didn't want to go that way.

I've figured out that a solution is to store the images in the same directory where the report gets generated, give the image name to .addScreenCaptureFromPath(screenshotName.PNG) and it works perfectly.
