Why don't you store image name in separate column, then it will be easy to retrieve.

VB

WHEN LEFT(convert(varbinary(8), IDOC),2)=0x424D THEN 'BMP'
 WHEN LEFT(convert(varbinary(8), IDOC),2)=0xFFD8 THEN 'JPG'
 WHEN LEFT(convert(varbinary(8), IDOC),2)=0x4749 THEN 'GIF'
WHEN LEFT(convert(varbinary(8), IDOC),2)=0x4920 THEN 'TIF'
