[Zope] Adding IMAGE with manage_addImage is impossible :)

[Alexander Staubo]

Are you specifying the encoding type? Images are binary and must be
base64-encoded by the browser. (There is also a raw binary transfer
method, but I forget whether it is supported by any browsers.) If you
omit the encoding type, Zope will not be able to recognize its file
type, and it will be handled as plaintext data.

Specify the form tag thus:

<form action="..." method="post" enctype="multipart/form-data">
  ...
</form>
