extracting the thumbnail from digital photos?

Al,

I ended up submitting a bug thinking that there was an issue with the 
offset command.   The offset command was fine, the bug was redirected 
against the livecode documentation as there is no mention of the 
relationship between the offset command and the casesensitive global 
property.

see...  http://quality.runrev.com/show_bug.cgi?id=14440

Did you happen to check the state of casesensitive before your test?    
I suggest that you try the code snipit that I used in the bug report 
below and if it really works with the casesensitive property set to 
false.   If it works,  then we really did find a bug in the Linux 
implementation.

on mouseUp
    put numtochar(255) & numtochar(216) into tStart
    -- in Hexadecimal: FFD8 = SOI(Start of jpeg image)
    put numtochar(255) & numtochar(217) into tEnd
    -- in Hexadecimal: FFD9 = EOI(End of jpeg image)

    put "AAA" & tStart & "DATA"& tEnd & "BBB" into temp1
    put offset(tStart,temp1) into tThumbstart
    put offset(tEnd,temp1) into tThumbEnd
    answer "Start:" && tThumbstart & cr & "End:" && tThumbEnd
end mouseUp
