Syncing Photos Mac To iPhone ???

Hi

When trying to sync photos from Mac to iPhone using iTunes it keeps deleting the previous images in Photo Library. Example, 20 images already in Photo Library, now i want to sync 20 more new images, the images sync but the previous ones in Photo Library keep deleting.

I've tried creating new folders in both the iPhone and iTunes to avoid this but it doesn't seem possible.

Are you using iPhoto to manage your images?

No the images are in a created folder in documents.

After a day of confusion I finally figured it out, Apple is certainly a complexed learning curve.

Thanks.

How did you solve this? I have similar problem
