<div>Hi Asif,</div>
<div>we have a similar problem and maybe the cause: During opencms 8.5.1 installation (Java 8) we got a warning: "image processing" doesn't work. Nevertheless I installed the opencms and i got no other problems. A solution is maybe to downgrade to Java 7 or change to OpenCMS 9.5.3 (in this version the bug is fixed). But i hope someone finds another solution under Java8.</div>
<div> </div>
<div>Regards</div>
