You missed out the last instruction in the readme for the avatar mod installation:
Quote from readme:
Look for this code arond line 796
if strCountry = "1" and trim(Member_Country) <> "" then
Response.Write " <font color=""" & strForumFontColor & """ face=""" & strDefaultFontFace & """ size=""" & strFooterFontSize & """><small>" & Member_Country & "</small></font><br />" & vbNewLine
end if
Directly above that add this code
if Member_Avatar <> "noavatar.gif" then
response.write" <img src=""" & Member_Avatar & """ width=""" & intAvatarWidth & """ height=""" & intAvatarHeight & """ border=""" & intAvatarBorder & """><br /><br />"
end if
