image error (..17.jpg): error parsing image file - image type not recognised, , not supported gd imagecreate

even, gd library installed in server using apt-get install php5-gd command. and, image path used correct.

i tried keep image source such. but, no luck.

<img src="<?= \yii\helpers\url::to('@web/images/logo.png', true) ?>" width="100" alt="logo" /> 

i searched , tried solution given these links. but, still no luck :

1. images not showing on production on local environment - github
2. mpdf 5.7.1 - image displays broken [x]
3. generated picture in mpdf
4. error parsing image file

any help/hint/suggestion appreciable.

most picture not available mpdf via generated url. let's try debug :) run following code on both local , prod environments

$imageurl = \yii\helpers\url::to('@web/images/logo.png', true); $image = file_get_contents($imageurl); echo (new \finfo())->buffer($image); // echo $image;  // ^^ uncomment, if previous line echoed not image-related.  // maybe, you've got 404 error
