Request Alt For Images From Thread Title

hello every one
i need an add-on to make the alt for (embedded attached images) inside threads is equal the thread title.

i opened 'bb_code_tag_attach' template and change the alt for embedded attached images but can not make it thread title because the thread title variable is not working inside this template

Code:

<xen:if is="!{$validAttachment}">

    <a href="{xen:link full:attachments, $attachment}" target="_blank">{xen:phrase view_attachment_x, 'name={$attachment.attachment_id}'}</a>
   
<xen:elseif is="!{$attachment.thumbnailUrl}" />

    <a href="{xen:link full:attachments, $attachment}" target="_blank">{xen:phrase view_attachment_x, 'name={$attachment.filename}'}</a>
   
<xen:elseif is="{$canView} AND {$full}" />
   
    <img src="{xen:link full:attachments, $attachment}" [COLOR=#ff0000]alt="image, photo"[/COLOR] class="bbCodeImage LbImage" />
       
<xen:elseif is="{$canView}" />
   
    <a href="{xen:link full:attachments, $attachment}" target="_blank" class="LbTrigger"
        data-href="{xen:link misc/lightbox}"><img
        src="{$attachment.thumbnailUrl}" alt="{$attachment.filename}"
        class="bbCodeImage LbImage" /></a>
           
<xen:else />

    <a href="{xen:link full:attachments, $attachment}" target="_blank"><img src="{$attachment.thumbnailUrl}" alt="{$attachment.filename}" class="bbCodeImage" /></a>
   
</xen:if>

therefore i need an add-on to do such thing
