#### Replace text with image in text widget

I'm trying to replace an emoticon with an actual image in a text widget.
I know I'm not doing this correctly: the sample code below inserts two
images randomly and seems to garble the text in other ways. The idea is
to have two emoticons (one on each line) and replace them with an image,
nothing more. Can anyone take a look and suggest how I might get this to
work? Thanks.

Found this code at the wiki which does the trick: proc replace_one {w str img} { puts "replacing" foreach {from to} [$w tag ranges hilite] {
$w tag remove hilite$from $to } set cmd [list$w search -count n -- $str insert+2c] set pos [eval$cmd]
if {$pos ne ""} {$w mark set insert $pos$w see insert
$w tag add hilite$pos $pos+${n}c
$w delete insert insert+[string length$str]c
$w insert insert {}$w image create insert -image $img replace_one$w $str$img
}
}

What is "text + text" supposed to do right now? It doesn't seem very useful to me. What about making "text + text" as an equivalent for "text || text"?
