I want to store and retrieve images from sql database in Delphi XE.

My code:

TBlobField(query.FieldByName('image')).SaveToStream(MStream);    
Image1.Picture.Graphic.LoadFromStream(MStream);

Don't forget to set the stream position to 0 between saving from the database and reading from the image.
