image type

can anyone help me?
is it a normal behavior of the plugin that the file type remains image/jpeg after conversion or it only happens to me

Thanks for reaching out @patrikmuse, and apologies for the late replay. When the plugin generates a WebP or AVIF version of an image, it’s using the -jpeg reference in the image you reference to help identify that the original image was a JPEG.

Regarding this appearing as a image/jpeg file type, is this from your hosting control panel or elsewhere? Please share where you’re seeing this file type and we can check further, or check how the image appears from an FTP program.

These are the metadata of an image converted with your plugin. Some sources remain as image/jpeg instead of image/avif, causing issues with certain plugins, such as this section of code from RevSlider:

// Check if $img_url is local.
if ( false === strpos( $url, $upload_url ) ) return false;

        // Define path of image.
        $rel_path = str_replace( $upload_url, '', $url );
        $img_path = $upload_dir . $rel_path;

        // Check if img path exists, and is an image indeed.
        if ( ! file_exists( $img_path ) or ! @getimagesize( $img_path ) ) return false;

        // Get image info.
        $info = pathinfo( $img_path );
        $ext = $info['extension'];
        list( $orig_w, $orig_h ) = getimagesize( $img_path );

        // Get image size after cropping.
        $dims = image_resize_dimensions( $orig_w, $orig_h, $width, $height, $crop );
        $dst_w = $dims[4];
        $dst_h = $dims[5];

you can see the image in media from my wordpress

Appreciate the additional screenshot @patrikmuse. I’ve been performing some checks on this and while the media file manager in WordPress may display the mime type as a jpg (example), this is only WordPress core referencing the original image, as noted in this comment on a related GitHub issue.

To summarize, the AVIF image is used, it’s just the original JPEG image may be referenced in your media manager, which may be more suitable, as opposed to displaying different formats of the same image.

Okay, all clear, but this behavior with converted images leads the plugins to unexpected responses, like this:

[10-Nov-2024 02:45:08 UTC] PHP Warning: Trying to access array offset on value of type bool in/public_html/wp-content/plugins/revslider/includes/aq-resizer.class.php on line 99 [10-Nov-2024 02:45:08 UTC] PHP Warning: Trying to access array offset on value of type bool in /public_html/wp-content/plugins/revslider/includes/aq-resizer.class.php on line 100

If I upload an image in webp or avif format, the plugin works correctly, but if I convert it with yours, this happens, and I can’t understand why. I get extreme spam of these warnings.


The code part is this

// Check if $img_url is local.
if ( false === strpos( $url, $upload_url ) ) return false;

        // Define path of image.
        $rel_path = str_replace( $upload_url, '', $url );
        $img_path = $upload_dir . $rel_path;

        // Check if img path exists, and is an image indeed.
        if ( ! file_exists( $img_path ) or ! @getimagesize( $img_path ) ) return false;

        // Get image info.
        $info = pathinfo( $img_path );
        $ext = $info['extension'];
        list( $orig_w, $orig_h ) = getimagesize( $img_path );

        // Get image size after cropping.
        $dims = image_resize_dimensions( $orig_w, $orig_h, $width, $height, $crop );
line 99       $dst_w = $dims[4];
line 100      $dst_h = $dims[5];
