Has anybody found out how to deal with unknown respond\_to’s?

for example:

```
 respond_to do |format|
   format.html # show.rhtml
   format.xml { head :status => :method_not_allowed }
   format.rss { head :status => :method_not_allowed }
   format.atom { head :status => :method_not_allowed }

```

will deal well with predetermined types (html, xml, rss, atom)

but I’d like to respond appropriately to say ‘format.jpg’.

any thoughts?

Create your own mime types. Topfunky shows you how –
