Add Image from custom Image field on Proposal to Advanced PDF/HTML template

I have created a custom transaction field where type=image. We upload images of various sizes and types.  I am trying to add the image to and Advanced template and have tried: <#if record.custbody_proposal_drawing?length != 0>${record.custbody_proposal_drawing}</if>, ${record.custbody_proposal_drawing}, <img src=${record.custbody_proposal_drawing}/>, and <img src="https://system.na1.netsuite.com/core/media/media.nl?id=/${record.custbody_proposal_drawing}" />.  I added the following to the CSS to account for various image size:
table.image td {
    vertical-align: text-top;
    max-width: 100%;
    height: auto;
    }

Any ideas how I can get this image field to pull into the template and control the sizing via css?
