Is there is any limit when getting image from cloudinary using url
There are no limits for this
You may have to upgrade to a Paid Plan if you exceed your Bandwidth of Cloudinary, but if you compress your Images enough on Upload it’s not a big Problem.
Yes it does. Every 1GB Download or Upload is one Credit on Cloudinary.
You should have at least 25 Credits with the free Version.
If you set you Upload presets to limit you Photos to 1080p and Quality to ECO, your Image Size is small enough to don´t exceed your Bandwith.
These are my Settings! You can find them under Settings → Upload.
