You mean e.g. this one: http://sourceforge.net/projects/zint/
Nice - allows for many different types of coding and saves to PNG/EPS/SVG, but i don't think it solves the OP's (both yeun & Martin) problem. The OP's already got the TIF image file which is to be placed in the drawing. What he's after is a way to insert that more automaGically than ImageAttach --> Browse to File --> Select --> OK --> Click Left-Bottom point --> Click Top-Right point ... for each drawing.
Basically something like this:
Code:
(defun c:InsertImage (/ filename found)
(setq filename
(strcat (getvar 'DwgPrefix)
(substr (setq filename (getvar 'DwgName)) 1 (- (strlen filename) 3))))
(if (vl-some '(lambda (ext) (setq found (findfile (strcat filename ext))))
'("JPG" "GIF" "PNG" "TIF" "BMP"))
(command "_.ATTACH" found "_Non" '(0. 0. 0.) "" ""))
(princ))
