Open the Developer Tools panel in the browser, go to the Network tab, find the image to be checked there and make sure that the header optipic-cdn is in the list of HTTP headers. If it is, the image was downloaded from OptiPic CDN.
Please note that it would be nice to have more stock on the account, so that new images will be automatically compressed, which will be added later on the site.
Absolutely transparent pricing CDN OptiPic
You pay for the optimization of only those images that are viewed by visitors to your site.
For viewing each image, 1 view is deducted from your account.
Write-off from the balance sheet takes place once a day (for the previous day).
As a result, the cost of using CDN depends on the number of images viewed.
On average, for an online store with a monthly attendance of 300,000 views (requests) per month, about 5 million image views (requests) per month are released.
Of course, this figure is individual for each site - it depends on which pages your site visitors visit more, how many images on each page of your site, etc.
