IMGHhaste's business model works with Unmetered bandwidth using Multi-CDN in more than 500+ worldwide locations.
When you request an image from imghaste, it counts as an Image Optimization Credit.
Then your image is cached on the Nearest Location for 30 days and it will not be requested again.
Isn't that amazing? Every other image service would charge you using Bandwidth or pageviews/sessions.
With imghaste you will be charged only once.
