Questions before using

Hi, thank you for reaching out.

See answers to your questions below:

1. Of course you can use cloudinary for oure CDN purpose and deliver the images “as-is”. However we highly recommended using Cloudinary end-to-end, meaning to upload high-res images to Cloudinary and use our optimization capabilities to gain the best out of your images. For example, Cloudinary supports browser detection based format optimization, a feature that requires adding the f_auto transformation to the image URL (The decision is being made on the CDN layer).

2. From you WP media-library you can select certain images and migrate them solely. And again, the best practice is to have all images delivered together from the same origin and using the same CDN.

3. You can select which images you want to be uploaded to Cloudinary. Please explain further how you want to go about distinguishing based on image size?

4. Cloudinary provides a jQuery based plugin for delivering images with the width matching the size of the containing element (e.g. div element). If your div tags are responsive, then different size of image will be delivered for any device that views the page.
More information and setup instructions are available here: http://cloudinary.com/blog/how_to_automatically_create_images_for_responsive_design

5. Free plan quotas can be seen on the pricing page.
