Images in a Grid column

["SIMM, Stephen (SOGETI HIGH TECH)" <st...@airbus.com>]

Hello, I'm would like to put a thumbnail image in a column of a grid (each row has it's own unique image).
The images are not bundled with the application, they're on another file server "behind" the one hosting my application.

I think I have a partial solution but it needs filling out.  So far I haven't found a cogent example for Tapestry5.

- Use BeanModel to add a column (in the page class) and reference the model in the grid  (following the "Adding Columns" example of the reference documentation (corelib/compontents/Grid.html):

    model= beanModelSource.create(MyObj.class, true, resources):
    model.add("thumbNail', null);

    <t:grid t:source="MyObjList" t:model="model" t:row="MyObj"...>
         <t:parameter name=thumbNailCell">
         ???
         </t/parameter>

Then I get lost.  I understand the Tapestry5HowToCreatePieChartsInAPage example (in the Tapestry Wiki) but it it doesn't seem to match what I want because it's not in a grid.  So...

How would I put the equivalent of <img src="${chart3}"/> in the <t:parameter tag and somehow pass the MyObj instance on that row so that my program knows which image file to get?

Where would I put the code to automatically render the image and return the InlineStreamReponse (like in Tapestry5HowToStreamAnExistingBinaryFile), in an onThumbNail type action listener in the page class?  This doesn't seem obvious to me since there is no action on the part of the user, the image should just be generated automatically.   Perhaps a Component class but I don't see how to trigger the use of that class.

Thanks for any pointers,
-Stephen
