So that, I tried this technique - Modify Default Image Name Suffix but it doesn't work as I need, I have all the images loaded, and I need to regenerate them. And what about the recovery of the images?
What I need is have the image files named as
pic-large.jpg, pic-medium.jpg, pic-thumbnail.jpg instead of
I use ImageMagick engine plugin and Additional Image Sizes (zui), in order to create more sizes than the default ones.
