Hello,
to avoid an “error” with W3C Check there should be after line 642 in the master-slider\includes\msp-shortcodes.php these two lines added:
'width' => '1',
'height' => '1',
And the line 725 (727 if the two lines before are added) should be changed to
$slide_content .= "\t\t\t\t\t" . sprintf('<img src="%s" alt="%s" title="%s" data-src="%s" width="%s" height="%s" />', $src_blank, $alt, $title, $src, $crop_width, $crop_height )."\n";
Maybe in the next update?
Best regards,
Harry
