How do I delete things off my iCloud? Like pictures?

You can go to http://www.icloud.com

Log in, and then click on your account name, then "Advanced". You'll be given an option to reset photo stream.

i found that but what about apps that backed up into icloud that i didnt want to. i need more space in my icloud but i dont really want to buy more.

Apps are not part of the iCloud back up

Hi I'm gonna try and do that and I hope it works too!... I want to delete photos that I had before and I heard that it would be best to delete it completely....Thank you, will let you know if it works...:)

To limit what is backed up to iCloud

Settings>iCloud>storage and backup

select your current device backup and all backed up content is listed below you can turn off what u want
