Visual problem with my photos and image on my website

Hi everyone,

First I’m glad you take a time for help me and I’m sorry if I make some mistake in english. I’m french.

Almost the last template update (jupiter) I got some problems on my website. Every photo didn’t pop up, my logo either and my image gallery aren’t good. I got the blue “?” instead of those.

I search by myself and find a plugin for maybe resolve the size of photo, I used Force regenerate thumbnails. That’s worked! I was happy to figure out that by myself. But everyday I have to do that… Like if what I did desappears during the night.

So I’m kind stuck. I learned my photo are too big but i should be surprise if it’s only that. My photo are between 50Kb and 400Kb. And I use png and jpeg. In my media I have some picture who doesn’t appear too like blue “?”.

All my plugin are update except those I didn’t use ( disactivate)
I give you a link for look my website: https://handbagsmadeinfrance.fr/woodbags/

I hope it’s not a big deal and you could help me.
Thank you
