I don't know what you mean by "putting an ad in", but in almost any Windows application I've ever seen, when you do a Save As you get a standard window that lets you select the folder to put a file in and a name for the file. If you're saving something from a camera, it will default to some folder usually one it creates inside the Pictures folder, but you can usually change that. The exact details depend on what you're saving from and what software you're using which is why I'm asking for clarification. To give specifics, you'll need to provide those details.
I am using windows Vista home edition 64 bit.
Say for instance I am putting a ad in and it says browse photos. I go on pictures and windows gallery is not a option. When you click on pictures it just shows my folders and my photo stream ( for my iphone photos) I also use picasa and that's not a option either. So I have to save every picture to my desktop in order to locate them and that is very very time consuming. Can anyone help me?
