PHP: Convert Image file content to blob image tag

For the mimetype, see Mimey or another lib like it.
Or this shortcut might work for some file types like png and jpg: $mimetype = "image/".pathinfo($path,PATHINFO_EXTENSION);

$path = //path/to/file.jpg (or whatever)    
    
$mimer = new \Mimey\MimeTypes();    
$mimetype = $mimer->getMimeType(pathinfo($path,PATHINFO_EXTENSION));    
    
$source = file_get_contents($path);    
$base64 = base64_encode($source);    
$blob = 'data:'.$mimetype.';base64,'.$base64;    
    
$html = '<img src="'.$blob.'" alt="Description for differently abled humans." />';    
echo $html;
