I have an image stored in MSQL.(Don't tell me its not proper do that,I know already).Anyways I need to display it in DTML.

 StockChartManagePreview (DTML)

 <dtml-var standard_html_header>
 <img src="StockChartManagePreview_Handler">
 <dtml-var standard_html_footer>

 StockChartManagePreview_Handler (python script)

 request = container.REQUEST
 response = request.RESPONSE
 photo = context.StockChartManage_getImage(ID = 6666)
 return photo[0].image.read()
 #I already tried - return photo[0].image
 #it gives an error image cannot be displayed because it contains errors

 StockChartManage_getImage (Z SQL Method)

 SELECT image
 FROM `imagebase`
 WHERE imageID =<dtml-sqlvar ID type="string">

 Now my problem is that Zope asks for a login every time I view the DTML (StockChartManagePreview )

 Please Help.
