How to get existed thumbnail path

I see that after I upload the image, cockpit generates thumbnail automatically to show in the admin area.

But when i am trying to fetch the image url of entry using API, i get only the original image url

I found out and tried thumbnail generator cockpit(‘cockpit’)->thumbnail($options) but it generates new thumbnail images, i want to get existing thumbs urls and use every time i do api call

If you use the same options a second time, the thumbnail won’t get regenerated. Instead you will receive the url to the previously generated thumb.

If you want more consistent thumb urls, you could give one of these addons a try:

Now I get it, thanks. Please add more info to the documentation, it’s very poor.
