This feature is useful if you want to upload many images to your at once, without needing to create new posts for each of them.
From your PostMyParty dashboard, click Post Library.
Click on the name of the library you want to add your images to.
If you do not yet have a library created, use the New Library button on this page to get that created first.
Select the Bulk Upload button at the top of this library.
Use the Browse File box to either upload images from your device, or drag-and-drop them.
After adding all images wanted to this library, click the Create Post(s) button.
Each image you had uploaded will now be listed as a post in that library.
