Fix Google?

Hello,

I am trying to improve my score at google speed, one of the remaining item is picture size.

I have one picture that is giving me headache as it keeps coming back at the size of 215ko while it is actually 122ko.

I was wandering the reason why google keeps on telling me about this picture that I have now deleted and changed with the lighter one in the media library?

For your information, I have deleted all caches.

Many thanks in advance for your feedback.
