the {(allptvs)} markup expression from the PowerTools recipe will list
all PTVsfrom the current page.
'Attach:my_photo.jpg|Some text' is read as a PTV, i.e. it follows the
Varname:value syntax.
So {(allptvs)} includes it in the listing.
Since no attempt to avoid markup rendering from markup present within
a PTV is made, the image shows.
The ShowHide will hide your image initially, but the markup is still
in the page, and {(allptvs)} picks it up.
