TwicPics doesn’t store any assets, it works as a proxy.
TwicPics is dedicated to media delivery and can be plugged on top of any storage. When an image is requested, TwicPics gets the image from your storage, optimize it, cache it, and deliver it. All this on the fly :)
In the case you don't have any upload/storage solution yet, we recommend using a block storage service like AWS S3 or Google Cloud Storage plus an open-source file uploader solution like Uppy so that you don't have to pay for unnecessary services.
Please refer to our documentation to learn how to set-up Twicpics.
