OK, this is my first experience with Paint.Net and I have a question in order that I may begin. I am currently using PICASA 3 and have all of the images on my computer which are not backed up on a external source located there. How do I, or can I, use Paint to edit an image in PICASA 3? If so, how do I do this? If this is not possible, what do I need to do in order to access and edit my images in PICASA 3 with Paint? Thanking any and all in advance for any help that you may be able to offer.
