OK, you had me intriged, I never done this before, simply because I have always been
told not to store images in the db, but what if I run into a db that does!? So I
needed to find out.
<cfsetting enablecfoutputonly="yes" showdebugoutput="no">
<cfsilent>
<cffile action="readbinary" file="C:\Temp\test.gif" variable="thisFile">
<cfquery name="qInsert" datasource="dsnTest_development">
INSERT INTO tblImage
(fileContent)
VALUES (<cfqueryparam value="#thisFile#" cfsqltype="CF_SQL_BLOB">)
</cfquery>
<cfquery name="qGet" datasource="dsnTest_development">
SELECT fileContent
FROM tblImage
</cfquery>
</cfsilent>
<cfcontent type="image/gif; charset=8859_1">
<cfscript>
writeOutput(toString(qGet.fileContent));
</cfscript>

Thanks for the info.
It's a bit more complex than I had hoped for, so I might try another work
around.
Good to know that it can be done though.
Thanks,
Phil
