Helen,

I can live with .bmp, no problem. The subtype is set to binary (0). Re:/
tIboSql: sorry, I meant tIboQuery. Re:/ linkage, tDbImage.DataField is set
to the name of the blob field of the FB table.

In case it helps, the D6 debugger stops execution on the line,
"FIB_Query.Name := 'IBOqr' + Name;", in IBODataset.pas.

Jack,
First thing, TDBImage supports only the Windows bitmap type (.BMP),
i.e. use it as if its real name was "TDBWindowsBitmapImage".

You will find the source for an IB_JPEGImage component in the Addons
directory of your IB installation. It's a contributed component (Thomas
Steinmaurer?) which I haven't used myself...and I don't know whether it is
usable with the TDataset-compatible persistent field. If not, I'm pretty
sure there is a TDBJPEGImage available on Torries.

Second thing, what do you mean by "tIBOSql"? Is this some kind of
derivative component?

Next, what sub-type of blob do you have declared for it in your database?

And, last, how are you linking the blob to the image component?

Helen
