Hello,I am working on a slide sharing application which lets people upload presentations and pdfs and shows them in the browser. The website is hosted on heroku and slides are being uploaded to AWS S3 using CarrierWave gem.Link: SlideSquareProblem: I am using Google Docs viewer to view presentations online right now, which fails to display .odp and .ppt, .pptx and related file formats. I have come across DocSplit Gem ( https://github.com/documentcloud/docsplit ) to extract images from ppt, pptx but unfortunately I have failed to implement it because Heroku does not allow write access to its system, and images can hence not be extracted in production.
Actually, you can write to a temporary directory on Heroku. You just can't rely on that storage being available past the end of the request. I've relied on this behavior for building PDFs and then delivering them to the browser with a Rails send_file
Depending on whether you pull images from PPT only on demand, this might be enough for you.

Please describe a suitable way to resolve the problem, while using Heroku. If not so, please provide good alternatives.The website is live here: http://slidesquare.herokuapp.comSource code: http: https://github.com/chi6rag/SlideSquare--
