I've tried adding a hidden field to the form:
<input name="Photo_Front" type="hidden" id="Photo_Front" value="http://localhost:8888/champion_nutrition/client_photos/<?php echo $WA_DFP_UploadStatus["WA_UploadResult1"]["serverFileName"]; ?>">
And also adding it to the email body (webassist/email/tamplates/Block_2.php):
<tr valign="top">
<th style="font-family: Arial, Times, serif; font-size: 12px;width: 190px; text-align: right; padding: 3px 10px 3px 3px; color: #666; font-weight: bold;"> Photo (Front):</th>
<td style="font-family: Arial, Times, serif; font-size: 12px;padding: 3px; border-left: 1px solid #DDD; color: #666;">http://localhost:8888/champion_nutrition/client_photos/<?php echo $WA_DFP_UploadStatus["WA_UploadResult1"]["serverFileName"]; ?></td>
Neither work.
