Hi hoolio,

I modified to the following: 



class logo_f5_class_t2 {
   "filename" { "/var/class/f5.image.class" }
}

rule TEST_IMG_t2 {
   when HTTP_REQUEST {
    if {[HTTP::uri] eq "/testimage/image.png" }
                {
           HTTP::respond 200 content [b64decode [class element -value 0 logo_f5_class_t2]] "Content-Type" "image/png"
                }
   }
}

however I still see the following error in the log: 



Mar  9 11:52:41 local/tmm6 err tmm6[6612]: 01220001:3: TCL error: TEST_IMG_t2  - conversion error     invoked from within "b64decode [class element -value 0 logo_f5_class_t2]"

The f5.image.class contains the following with no new lines (I used :%s/\n//g to remove new lines):
