Embed images into template HTML Velocity in loop

Question

I know how to embed an image into a template. See this question. My question is how to do it in a loop:

<table>
     #foreach( $object in $objects )
        <tr>
            <td>
                <img src="cid:${image_cid}"/>
            </td>
...

The problem is I need to create a dynamic unique cid placeholder, e.g.:

<img src="cid:${object1_image_cid}"/>
....
<img src="cid:${object2_image_cid}"/>

I've tried using a variable inside of the ${image_cid} variable, but that just crashes. e.g. I tried

${$object.id image_cid}

Any suggestions or ways to solve this?

Something like that yes. Generate all of the cids and stick them on the object? Hmmm — Brian Kates, Aug 03 '16 at 16:26
Maybe you need to take a look at http://stackoverflow.com/questions/18941773/how-to-add-image-in-email-velocity-transformer-templates-from-classpath — Ismail RBOUH, Aug 03 '16 at 16:27

Thanks to Ismail for this suggestions. Here's what I did. In my Java code, I set all of the cids in a transient field on the object, e.g.:

for ( Object object : objects ) {
        String artworkCid = email.embed(file);
        object.setCid(artworkCid);
}

Then, in the template:

#foreach( $object in $objects )
      <tr>
            <td>
                <img src="cid:$object.cid" />

(obfuscated everything to object)
