If there will be images, then having some way to size them seems sensible.

According to RFC 3986 character definitions, the VERTICAL LINE is neither in the set of reserved nor unreserved characters, which means it is forbidden inside a URI if not escaped.

This is an issue in your email client. But I use an entirely different client than you do, and it exhibits the same issue. Using SPACE instead of VERTICAL LINE as the separator for the image size would avoid this. There is no history in perlpod of using multiple VERTICAL LINE as part of a single formatting code, so using a new delimination character for a new kind of attribute (the size) might be appropriate.
