[Zope] Viewing a Blob using DTML

[working4aliving]

Thanx Matt and Maik... You both steered me, and it works... (needless to
say, I'm pretty damn happy right now :))) )
Seems like I didn't need the RESPONSE.setheader (yet???)

Here's the method (requestImage1)

<form action="selectImage1">
<input type="text" name="Id"><br>
<input type="submit">
</form>

Here's the python script(selectImage1)
#image1 is the name of the field
result = []
lob = ['image1']
for row in context.sql_db_image1(id=id):
  lob = row['image1']
return lob
