Is it possible to regenerate all previews with the required size based on a large picture?

Question

PHP

The site on 1C-Bitrix has changed design and the announcement pictures for the new design turned out to be too small, is it possible to regenerate all the announcement pictures based on the detailed picture of the main news?

Answer 1

Can. You just need to write a function for this, which will go through all the news, take the detailed picture and put it in the preview. In general, it is bad practice to store cropped images in previews or detailed ones, it is better to reduce them directly in the component, then the sizes can be changed at any time and you won’t have to bother with transferring images.
