I have created a custom post "event" which contains a gallery of photos.
So I need to create a custom field "image".
I want to:
- limit the number of images
- limit the size of the images
- set the location of the images
The custom fields "image", single image", "advanced image", "image upload" can do 2 of them, but none can do the 3 features at the same time.
How I could do that?
