not possible. i had many a long talk with many people at devcon about this
very issue. unfortunately cf's binary handling is not the best. i use php
on linux to do all my image/binary stuff. to use cf, you need to write to
the hd. also uploading images to the db is done in base64, you need to write
some sp's to convert from b64 to bin on the db. i don't recommend storing
bin objects in the db as b64, less efficient (~30%).
good luck,

Subject: binary stream (image) output to the browser
Hello there... does anyone know if it is possible to write an image stored
in a variable, directly to the browser without writing it to the HDD first?
<cfif server.os.name eq "Windows NT">
<cfobject type="COM" action="Create" class="top10.genmap"
name="Bitmapper">
<cfset picture = Bitmapper(coords)>
<cffile action="WRITE" file="C:\Inetpub\wwwroot\test\#coords#.jpg"
output="#picture#" addnewline="No">
<cfoutput><img src="#coords#.jpg" border="0"></cfoutput>
</cfif>
this works... but how can i get it to work without the cffile action?
