following examples found here I have this route  
`
$app->get(’/fileimg/’, function (Request $request, Response $response, array $args) {
$file=“C:\data\imgs-campione\350x150.png”;
if(!file_exists($file))
die(“file:$file”);
$image = file_get_contents($file);
if ($image === false)
die(“error getting image”);
$response->write($image);
return $response->withHeader(‘Content-Type’, ‘image/png’);
});
`  
I tried with many files of differents format

Chrome always display a blank screen with a small square in the center

firefox output a msg like : image can’t be displayed because contains errors

but if I run this code in a script outside Slim  
images are outputted correctly in both browser

`
<?php
$file="C:\\data\\imgs-campione\\uhd-1.png";
if(!file_exists($file))
```
die("file:$file");

```
header(‘Content-Type: image/png’);
readfile($file);?>
`

Hello @aghezzi

I tried your code and it works fine (in Chrome and Firefox) 🙂

```php
$app->get('/fileimg', function ($request, $response){
    $file = __DIR__. "/aaa.png";
    if (!file_exists($file)) {
        die("file:$file");
    }
    $image = file_get_contents($file);
    if ($image === false) {
        die("error getting image");
    }
    $response->write($image);
    return $response->withHeader('Content-Type', 'image/png');
});

```

I just spent an age with the exact same symptoms.

In the end it turned out I had a byte order mark in my index.php file. This is easy to spot in vim:

I should have noticed that my IDE was highlighting it slightly different (notice they grey)
