Picture in header "blinking" when switchin between sites

When switching between pages on my website a icon picture I placed in the header is reloading with every switch, which results in the impression of a blinking picture when switching sites.

Everything else except content (rest of the header, background image) just stays as it is while loading a different page, but this image is always obviously “reloaded” which in my opionen just doesn’t look good. Is there a way to prevent this, so browsing my site will be a smooth experience?

Thank you guys.
