If you worry that the image data includes something that may cause the 
database do something else than just insert the image, then see to 
base64 encode it first, this way you will not be affected by the 
content, of course you make things a bit more "heavy" for the system as 
you will need to decode the blob each time you want to use the image, 
but then if you use some sort of cache then you can store the decoded 
blob in the cache and use it as long as it residence there.
