Multiple image previews needed for Dropbox integration with Ruby on Rails web app. (Chooser like functionality)

[Aditya S.]

I want to integrate Dropbox with my Ruby on Rails app. I want users to choose files which they want to import in the web app. Is there any way to get links to preview/thumbnail of multiple images. I want something like Chooser but the design will be my custom design so I need links for image thumbnails to display on my web page. Please guide me how to achieve this.

The /thumbnails endpoint can get you a thumbnail for an image.

To elaborate, you can use /thumbnails to get a thumbnail for an image as Steve said, but there's currently no way to get multiple thumbnails via a single API call, so you'll need to call /thumbnails repeatedly as necessary. We're tracking this as a feature request though.

The Dropbox API now offers the ability to get thumbnails in batches:

If you're using an official SDK, there will also be a corresponding method for this endpoint.
