I'm currently submitting my app for review and I've uploaded the main screenshot, but am unsure of how to get my additional screenshots to appear in the correct order. You have to select them all before uploading and there's no indication of what order they will be in!
Can someone let me know whether you need to select the screenshots in correct or reverse order?
Add them in reverse order.
So if the main screen shot is ss1.jpg
add the others in this order ss4.jpg ss3.jpg ss2.jpg
Then hit the upload button
Hope this helps
People should know that this post is very outdated. iTunes Connect now lets you drag and drop images in whatever order you like, and Apple doesn't reverse anything.
Mick is 100% correct. It boggled us at first too (keep in mind iTunes Connect is slow so having to upload it again was a drag...)
