I am doing a collage project and I need to print many many pictures for it. Since 4x6's are the cheapest that is how I want to go about doing it. But the photos I need have to be much smaller than a 4x6. I have them all re-sized correctly and I know that there is somehow a way to put them into a 4x6 template so that there is white space. So that when I have them printed I can just cut off the extra white space and have the correct size photo that I need. But I'm not exactly sure of how to do this. I do not have any fancy editors but I'm willing to download any free ones or use an online one. But can someone please give me instructions! Right now what I have on my computer is microsoft paint and picasa. If I didn't explain this good enough let me know and I'll try to rephrase myself better because I know this is probably confusing. Someone please help?
