How to display image in blob field in ResultSet in SiteStudio?

Question

I am running Site Studio 10gR4. For a custom page, I created a component that basically runs a query. The structure of the underlying data is a combination of Varchar2, Date and a single BLOB field. The blob field either contains a simple jpeg image, or nothing.
In my Page where I am looping through the data, how do I display the blob as an image?
Currently the code looks like this:
     <!--$loop SQLRoutes-->
          <tr>
               <td><!--$getValue("SQLRoutes",rsFieldByIndex("SQLRoutes", 0))--></td>
               <td><!--$getValue("SQLRoutes",rsFieldByIndex("SQLRoutes", 1))--></td>
               <td><!--$getValue("SQLRoutes",rsFieldByIndex("SQLRoutes", 2))--></td>
               <td><!--$getValue("SQLRoutes",rsFieldByIndex("SQLRoutes", 3))--></td>
               <td><!--$getValue("SQLRoutes",rsFieldByIndex("SQLRoutes", 4))--></td>
               <td><!--$getValue("SQLRoutes",rsFieldByIndex("SQLRoutes", 5))--></td>
               <td><!--$getValue("SQLRoutes",rsFieldByIndex("SQLRoutes", 6))--></td>
          </tr>
     <!--$endloop-->Field 1 is a blob and fields 5 and 6 are dates.
So really two questions:
1. How do I display field1 as an image?
Example:
<!--$getValue("SQLRoutes",rsFieldByIndex("SQLRoutes", 1))-->doesn't do it. Is there a different function then getValue() that I should be using to get the blob contents?
2. I want to compare the date fields to todays date, and either change the color or conditionally display the fields. I could do this with basic taglibs from jsp. How do I do this with IDocScript?
Example:
<!--$if getValue("SQLRoutes",rsFieldByIndex("SQLRoutes", 6)) > dateCurrent-->
  <span class="red"><!--$getValue("SQLRoutes",rsFieldByIndex("SQLRoutes", 6))--></span>
<!--$endif-->Thanks, Ken

I actually don't know the answer to #1. If I were to guess, there's nothing out-of-the-box to handle blobs, so your best option is to write your own idoc function. Take a look at the How To component if you don't know how.
For #2, you almost have it right. Insert bold:
&lt;!--$if <b>parseDate(formatDate(</b>getValue("SQLRoutes",rsFieldByIndex("SQLRoutes", 6))<b>)) gt</b> dateCurrent<b>()</b>--&gt;
&lt;span class="red"&gt;<!--$getValue("SQLRoutes",rsFieldByIndex("SQLRoutes", 6))-->&lt;/span&gt;
<!--$endif-->
