but still have same problem. web.config file:

<?xml version="1.0" encoding="utf-8"?> <!-- more info on how configure asp.net application, please visit http://go.microsoft.com/fwlink/?linkid=169433 --> <configuration> <system.web> <httphandlers> <add verb="*" path="*.jpg,*.gif" type="watermark" /> </httphandlers> <compilation debug="true" targetframework="4.5" /> <httpruntime targetframework="4.5" /> </system.web> </configuration>
