* Very great plugin thanks.
* There is an incompatibility with WordPress standard functions.
* If your plugin is active, then overwrites the standard the_post_thumbnail function
of wordpress.
* When I use this in my template:
`the_post_thumbnail('my_thumbnail_teaser');`
the result with your plugin not active is: `
`
* But when your pugin is active then the result is:
`
`
* Do you have a solution?

* Ok, I answer myself 😉
* The problem is the filter:
`add_filter( 'wp_calculate_image_srcset_meta', '__return_null');`
in the icp-functions.php. This filter strips all image attributes for all images
in the page, also srcset etc of images that not are in the carousel.
* My solution:
a) I have deleted the line with the filter b) then before this
line: `$output .= "{$image_output}
";` I striped
the code in $image_output with:
* ```
$image_output=stripImageAttributes($image_output,'srcset');
$image_output=stripImageAttributes($image_output,'sizes');
```
* Function stripImageAttributes:
* ```
function stripImageAttributes($html,$stripAttribut)
{
// init document
$doc = new DOMDocument();
$doc->loadHTML('' . $html . '');
// init xpath
$xpath = new DOMXPath($doc);
// process images
$body = $xpath->query('/html/body')->item(0);
foreach ($xpath->query('//img', $body) as $image) {
$toRemove = null;
foreach ($image->attributes as $attr) {
if ($stripAttribut == $attr->name) {
$toRemove[] = $attr;
}
}
if ($toRemove) {
foreach ($toRemove as $attr) {
$image->removeAttribute($attr->name);
}
}
}
// convert the document back to a HTML string
$html = '';
foreach ($body->childNodes as $node) {
$html .= $doc->saveHTML($node);
}
return $html;
}
```

* Now works for me.
* Maybe you can integrate a similar or better solution into the next version.

* Hi [@dimizu](https://wordpress.org/support/users/dimizu/)
* Thank you very much for your solution, really appreciate it 🙂
I’m going to
have to dig around in the code a bit and apply it in the next release…
