how to get pictures from iphone 4s to iphoto?

I am unable to get the pictures from my new iPhone 4s transfered to iPhoto on my iMac (version 10.5.8).

It does sync via iCloud to my iPad, but it will not transfer pictures to iPhoto when connecting the phone to my iMac. The phone doesn't appear on iPhoto... I don't have iCloud on my older iMac. It is not very impressive if you must have iCloud to be able to get pictures from iPhone 4s to iPhoto!

Any ideas?
