The option to schedule multi-image posts might not be available on every social account, due to each social network's limitations and their integration with third-party apps such as Postcron. Below we will list the social accounts that support multi-image posts on Postcron, and the maximum number of images per post for each of them:
Facebook Pages: Up to 140 images
LinkedIn Pages and Profiles: Up to 9 images
Twitter: Up to 4 images
Instagram (Business): Up to 10 images
When scheduling multi-image posts on several social networks at the same time, you won't have to worry about the number of images for each account; Postcron will adjust the number of images on each post according to the social network's limits!
For instance, if you schedule a post with 9 images on Facebook and Twitter at the same time, the Twitter post will be scheduled with the first 4 images uploaded.
Just make sure to organize the images in your post with this in mind, and Postcron will do the rest for you!
