How do I put multiple pictures on my desktop? for mac and PC?

Are you discussion about multiple pics at impossible to tell apart time, or a slideshow?



On a Mac you go into system preferences, nouns whatever pics you want by select Decktop. They can then appear surrounded by random charge as a slide show.
I am not real techie.. but, In days gone by I have arranged them as a collage contained by Power Point, saved the directory and used it as wall paper.. my other likelihood of choice is using slide.com... good luck.
Paste them together beside photochop or Windows Digital Image, savem as a jpg and use as a wallpaper
