How to customize the image control in form builder?

Hi, all

Using the image control in your, we can click  the "Browse" button and choose a local image file and upload.  I want to choose a file from our repository and put the URL of the chosen file into an element like:

  <control-1>http://localhost/images/path/to/my/image/file</control-1>

We have already wrote a popup window to browse and choose files in our repository. The remaining things are how to let the "Browse" button pops our window and don't upload.

I've read the code of "typed-controls.xbl", but don't how to start.  Can anyone give some suggestion? Thanks in advance.

To be fair it's not that easy! With the latest code, upload of
attachments is handled partly here (see the xf:upload):

and partly on the client-side:

Thank you, Eric.

Now I encounter another issue when using javascript: can the javascript get event property?
For example,

<xf:var name="control-effective-id" value="some-dynamic-data"/>
<xf:trigger  id="myButton">
        <xf:label>Browse... </xf:label>
        <xf:action ev:event="DOMActivate">
                <xf:dispatch name="selectImage" targetid="myButton"  >
                        <xf:property name="control-effective-id"        value="134314"/>
                 </xf:dispatch>                                                                               
        </xf:action>
                                                                       
        <xf:action ev:event="selectImage">                                                                                 
                <xxf:script>
                       
                                var element = this;
                                var event = event;
                                // Can I get  control-effective-id here
                </xxf:script>
        </xf:action>
</xf:trigger>
