Introduction

Image Upload is designed to cater to images. Uploaded images will be displayed according to dimensions set.

The Image Upload is only available on Professional and Enterprise Edition.

File uploaded through the Image Upload is stored under "[Joget Installation Directory]/wflow/app_formuploads".

How to set to a different storage path?

There are 2 ways you can change the wflow folder path:
1. by adding "-Dwflow.home=PATH" to your JAVA_OPTS when starting tomcat.
2. by setting the "Uploaded File Storage Base Path" option in General Settings.
