This one has me stumped.
Uploading an image, via ACF as usual, but I need to create multiple sized versions of that same image.
I could just use the regular add_image_size but, this means any other image uploaded, also gets created at these sizes which is not what I want (there will be around 100+ post_thumbnails created each time).
So, my question:
Using ACF to upload an image, how would I then create multiple sized copies of that image?
