Mixed content issue with insecure image

Since switching to cloudflare my website shows the mixed content error. i already had SSL insecure content fixer plugin installed, but the problem persists.

I tracked the issue down to the following error:
(index):1 Mixed Content: The page at ‘https://samidolls.com/en/shop/’ was loaded over HTTPS, but requested an insecure image ‘http://i1110.photobucket.com/albums/h459/SamiraminaMulticolor/Website%20Images/Logos/Etsy%20banner_zpsvdlvbduc.jpg’. This content should also be served over HTTPS.

but I have no idea where to find or edit the link. Any help is appreciated, thank you.
