I add a lot of images using the campaign. I set it up using the repost tool from IG and send the extracted images to my campaign where it is scheduled to publish 1 image per 3 days,.
I don't know personally know the images I'm using but I'm using semi popular good looking celibrity that is not well known.
I just extract all images from an account and send them to the campaign, I then go to the post list and delete the images I don't like.
As mentioned, I extract images using the repost to my campaign and use the when to publish tab to schedule my posts.
Yes, get NY proxy if your account is from NY so that you don't have issue logging in. Also, always use private proxy and keep it as long as you can.
Send to campaign tab is located in the Repost Settings
