Dear Robson,

Saving an image to a TBlobField can be accomplished with a TBlobStream. See the posting,

Re: save jpg to blob field -- Michel, 07:00:12 03/31/00 Fri

to see how it is done. Make sure the BlobStream is free'd after loading or saving. Also, if you want to have different image formats in the same table, you must have the image type (probably the extension) in another field.

I do not use quick reports, but by looking quickly at the documentation, TQRDBImage component has a picture property, which states that can support any VCL supported graphic. Envision is built with the VCL TGraphic framework. For example, when you include the EnReg.Pas in a uses clause, all the formats defined in the Envision.Inc file are registered. This should allow you to easily load any Envision support graphic in TQRDBImage:

QRDBImage.Picture.LoadFromFile('c:\images\photo.png');

Best regards,

Michel
