Hello Boyink! &Shane;
Actually, it was a bug and it has been fixed. I just found it here: https://support.ellislab.com/bugs/detail/17392
As due to the nature of my site, each photo is an entry so the first time when I tried to pull the photos, nothing showed up, I thought the site parameter doesn’t work. Second time I tried but a blog post, only text showed up, so I did some search on “MSM images doesn’t show up” and found the solution.
Everything is working as expected now.
Thank you guys 😊
Anyway, I still want to know the answer for my questions. For example I don’t want to “waste” 1 site just to hold 1 channel’s entries or for organizational purpose, how can I export and import entries between sites?
Thanks!
