hmm, should be possible, this would be an easie method, but not 100% perfect (Problem when first word is bbcode or image or smilie)

open your admin/functions.php
find in getpostbit section:

PHP Code:

    $post[message]=bbcodeparse($post[pagetext],$forum[forumid],$post[allowsmilie]); 


below add:

PHP Code:

$first=substr($post[message],0,1);
if($first!="<") $post[message]="<img src='{ imagefolder}/".$first.".gif'>".substr($post[message],1); 


then create a.gif...z.gif.
this version does NOT ignore capital letters, so you have to add also A.gif....Z.gif
