Several times over time I changed sizes of thumbnails WP generate when images are uploaded, always setting bigger size.
I have a lot of uploaded image files and image sizes. So it would be better to organize media files into folders based on post type. I have just read this tutorial, but as I can see it works with plugins. How to change this to use in a theme?
In 3.4 I used the following function to change image upload folder by post type.
Different upload directory based on post type in a theme
Now it doesn’t work anymore in 3.5. Do you have any idea how to replace this function in 3.5 version?
