Regenerate Thumbnails in 8.2 or 8.2.1

[Sancho Pantches]

I can not regenerate thumbnails in 8.2
I have about 600 products and I am attempting to regenerate the thumbnails from the default large_default size to  700 px x 916 px
- No matter what I do I either get an time-out error or afterward I immediately get the green message "The thumbnails were successfully regenerated.", when i fact they are not regenerated. 
- I also select the "Use WebP for all images" but the front still displays default jpg (800x800)
- I tried clearing the cache but still no luck. (also on the server )
Did anybody found solution for this?
Or I have to buy that module they sell for this issue?
Kind regards


My php.ini is
opcache.enable=1
opcache.enable_cli=1
apc.enable_cli=1
opcache.save_comments=1
opcache.revalidate_freq=1
opcache.validate_timestamps=0
opcache.interned_strings_buffer=32
opcache.max_accelerated_files=10000

allow_url_fopen=on
display_errors = Off
max_execution_time = 120
max_input_time = 700
max_input_vars = 10000
memory_limit = 512M
post_max_size = 256M
session.gc_maxlifetime = 10000
session.save_path = "/tmp"
upload_max_filesize = 128M
zlib.output_compression = On

Hi,

The standard regeneration of images in Prestashop does not work properly for many images because it is a cpu and disk intensive operation, clearing cache will not do the trick.

You need a module that does that operation more efficiently - yes like QuickUpdate

Yeah sure not a problem.

Hi,

To generate thumbnails without constraints, there are some very good free modules, such as this one: https://boutique.comonsoft.com/gb/free-prestashop-modules/27-regeneration-of-prestashop-images.html

After that, generating WebP image files retains the JPG extension, which isn't really a problem, but it does mean that browsers cache the original image, so that when your browser's cache is refreshed, you won't be able to view the image in WebP format.

Thank you Mediacom87.
That one was excellent
