* The `.Use` of storageHandler before setting up the template renderer causes a panic if there is an error to log. * The error passed to `ctx.Error` in that case may contain sensitive information and should not be rendered to the end user. We should instead log the error and render a simple error message. * There is no handling of missing avatars and this needs a 404. Minio errors need to be mapped to standard golang errors such as os.ErrNotExist. * There is no logging when storage is set up. Related #13159 Signed-off-by: Andrew Thornton <art27@cantab.net>
