How to massively increase the size of the pictures?
I need to massively increase the size of images in a folder. But the pictures are in different subfolders.
The only thing I know about them is that the title is 970, this figure is appended to the right pictures.
I need from the folder and subfolders to get all the pictures, the title of which contains 970 and increase to a minimum of 400 pixels on the smaller side.
Yes, and you need to record at the same location under the same name.
For example, there is a picture 37.970.jpg size 250х200.
It must be 37.970.jpg size 500х400.
