Is it possible to attach multiple images in a single post?
Yes. When you're publishing a post, you will be able to attach four images along with your content. However, you will only be able to add multiple images while posting on Facebook, Twitter and Instagram. Google+ and LinkedIn do not allow for multiple images to be attached in a single post on their networks,
To attach multiple images to your post, click on the "New Post" button. Once you're done composing your message, click on the camera icon at the bottom of the screen and you'll be able to choose the images you want to add. Then, hit "Post now" to publish your content, or schedule it for later.
How can I add a picture as a URL?
Sorry, you cannot hotlink an image from the web while composing individual posts. The image should be uploaded from your computer or mobile device. However, you can add pictures as a URL using the Bulk Scheduler.
