Hot to spot thumbnail in code?

Hello,

I’m trying to understand, wheater the generated thumbnails are actually being used.
Question is, how to spot it, eg. in chrome?
How to make the correct image size load?

In the code, I can see some numbers like 300w or 700w, but when loading it still feels so slow.
And the network is showing the big image is being loaded.

I’m just confused.

Regards
