Hi Chathura, The Activiti sends the Image as a InputStream. I convert it to a byte array String at the back end and once receive it at the front end UI component, I convert it to data uri byte array String. This way we will not need to write it to temporary image file. Instead we can straightaway set the data uri to image src attribute, which will render image at the jsp page.
Please find the patch @ https://wso2.org/jira/browse/BPS-481 Thank you & Best regards, *Amal Gunatilake* Software Engineer WSO2 Inc.; http://wso2.com lean.enterprise.middleware
