How to get pictures of my iPhone and onto my computer?

I have cleared off the pictures on my iPhone once and put them on my computer and it worked absolutely fine, but when I went to do it again, it says I don't have any pictures on my phone. If you could help, that would be great!

Just email them to yourself and save them from there

Take your charger and take the top off so you have just the wire and plug it into your computer and it wil ask if you want to import pictures. Then click yes

Plug your phone into your computer and sync it through iTunes. The photos should automatically transfer when you do this. It probably helps if you have an iMac or MacBook and are using iPhoto, but even without that if you sync through iTunes the photos should transfer.
