The images get cached by the store URL. So if the Store URL
setting in your store (Administration -> Configuration -> Stores
) is different from your actual store url your pictures might be cached to the value of the setting.
Fixing that setting and clearing your cache should fix your problem
Hope that helps!
thanks, yeah that's the thing. I think I have it setup correctly...right?
As you tick the ssl checkbox. So give the secure link of the shop. You must have the SSL certificate at the server. Then you have to enable "Force SSL for all site pages" from general setting. Otherwise, your cart,checkout, login and admin panel will not work.
If you do not have ssl certificate then simply uncheck the ssl and do not need to check the "Force SSL for all site pages" from the general setting.
After complete this setup, you need to clear your cache from admin side.
