Bird--
Given your new computer (at which you have become, by now, truly expert; right?!), I assume you have "PictureIt! 2000" or '99. Once you get a picture open by doing either file/open or clicking on one of the options on the "home page" which PictureIt loads, then you can either do "file/save as" at which point you get "options" as an option, or you can right-click and get a pretty complete menu which includes a save-as sub-menu. The right-click gives you a lot of choices which the menu bar does not. To do your collage, do "file/new blank picture" then "done" (at the bottom left) then "add something" then picture" then drill up or down through the C: drive directory structure to find a picture, add it, do it again, etc. In classic Microsoft fashion, IMHO, the program is not especially intuitive, but if you're not one of the lucky stiffs with Photoshop, it's not too bad once you get used to its navigation foibles. Is the collage for us?
