[xwiki-devs] How to insert an image programmatically into the inline form and the image will show up when the create post inline form shows up

Hi, all, I am playing around with the blog post application, when users click the create post button, it brings up the inline form for users to put text in, I have another requirement, we need to write some velocity code somewhere to retrieve an image url from a database, so when the inline form shows up after users click create post button, the image automatically shows up in the inline form, users then type in more text, my question is where should I put the code in? also the BlogPostClass and BlogPostTemplate have TextArea objects, which create GWT inline form, this is where I need to put image in programmatically, so I am thinking about accessing the GWT code to insert image, could anybody point me to the right direction about how to approach this to put image into the inline form programmatically? Thanks David
