[pmwiki-users] how to hide upload links for nonexistent attachments

Hello again. I'm trying to do something that ought to be simple, but
I'm not sure how to go about it...
I'm writing a pagelist template and want to display an image whose name
matches the name of the listed page if that image exists, and not
display anything at all if the image doesn't exist. But
Attach:{=$Name}.jpg and (:thumb {=$Name}.jpg:) both display an upload
link if the file doesn't exist.
If there's a function somewhere that determines whether a specific
attachment exists -- which there may be, since links are treated
differently on that basis -- then I could write a conditional to test
that function, but the only one I can find is AttachExist(), which only
tests whether the current page has attachments or not.
...or would it be easier to change the upload link format on these pages
(but not on other pages) so that upload links are hidden? Ideas
welcome. Thanks! --Ben
