Form pass through html > how to reach image attachment

Hi, I have a form with option “Render pass through HTML in Notes”.

form has field "$DelayedImagesOK " = “ok”

and rtf field “attimage” with attachment

then I have text “pass thru”

computed field has formula @If(@Attachments = 0;“”;“<img src = "0/” + fldThisDocID + “/$FILE/” + @AttachmentNames + “" width = "200px" height = "1000px">”)

unfortunately no image is displayed just empty red rectangle,

please, could you why image is not displayed properly?? is there problém with path or something else

ps - i db i have view “0” as well. this view contains just one column displaying doc id…
