How to delete many pictures at once on an iphone 4?

So I'm trying to get more storage on my phone and take off things that have a lot of space. Is there any way I could delete many pictures at once on my iphone. I have an iphone 4 and I have any pictures on my phone, prob around 2,000.

First open your photo album. At the top corner of your screen is the word "Select". Tap that then you can click on multiple photos in a row. Keep selecting photos until you've chosen all the ones you want to delete, then tap the little trash can on the bottom of your screen and it will delete all the ones you have selected. Hope this helps!

Use iCloud - free - to move your pictures (automatically) to your computer. You can still see them all on your phone even when it is disconnected from the Net but if you then delete every single photo in your Camera Roll (or least most of them) you will not be burdened with duplicates. HOWEVER - you have maybe month to SAVE them on your home computer, in folders, etc., or they will be automatically deleted. You decide what HAS to stay in your phone and what gets sent home. Experiment with this and see if it works for you.
