I don't know if the converting to image solution is what Nicole intended.
I'd handle it as a PDF for as long as we can.
This has the option to download it as a PDF and is easily attachable to the generated PDF when we export it.

I'd put it on INT for now, then she can decide if she wants it like this.

Minor nitpick, that I'd split it in 2 methods and call them conditionally. If you want to prepare the path for further filetypes, you could do it something like this:

case receipt_param.content_type
when /image/ then attach_image
when 'application/pdf' then attach_pdf
end

Yes, I agree with you, this isn't very clean.
However, the problem is that the pdf has to be inserted into the export of the expenses as pdf somehow. This is where it gets tricky with the pdfs. I guess maybe we could somehow just insert the pdf plainly after the page which is describing the expense...
