Subject Re: deliver attachment in show function?
Date Fri, 28 May 2010 11:21:36 GMT
Even more confusing:
GET /images/a0cbe43b55828d33320cf6cbd40bdb81?attachments=true
does include the data part base84 encoded

and return {
	base64: --data;
}
works as well.

why is the combination of those not possible?
