Image cache

[gianlucavef5ca]

Hello to all, i have a problem with the img cache of magento. 

So i have a lot of product with a lot of image, when i change 1 img, still the img remain the same, to fix this i have to go on the server, delete the cached img and flush the cache. 

there is a way to avoid it and when i publish an image appear correctly on the product?

thanks to all

after image update on product, you need to flush
Flush Catalog Images Cache and full_page cache and from admin

the button to flush the Flush Catalog Images Cache is at bottom of the cache management screen. 

NOTE: you also need to flush any CDN Cache if you have configured any. 

kindly accept as a solution if this works for you and give Kudos

but this command how much time will take? it will update all the image or just the updated ones?
