Render small files large to print clear/non-pixilated prints

[TadPops]

I want to make some of the pictures I have taken at e-mail size and render them larger in order to print them larger (5x7 to 8x10) and non-pixilated. Ulead used to have a choice for doing this back in the version that worked with Windows 98, but I cannot find how to do this in my Corel Digital Studio 2010. I did find in the media tray a way to save larger, but the file size did not change (and in some cases got smaller!), and I still got the same message upon attempting to print - that the file was too small to print at the size I wanted to. I understand the logic in the internet world we live in to make digital pictures smaller for emailing and web sharing; however, there are still times people want to hard copy print (like to send to their grandparents who don't even know how to turn on a computer, let alone surf the web) and there must be a way to do this when we are forgetful and don't reset our cameras! Any help is greatly appreciated, as an hour of searching the knowledge base and the board before registering was not helpful. Thank you! TadPops

I'm afraid if you have a picture that measures 3" x 2" and contains 850 pixels, you will never make it 10" x 8" and contain 5,000 pixels so that it remains clear and non pixelated.
Your best bet is o print it to the maximum size you can with it remaining relatively clear, and this can be done with trial and error and by gradually increasing the size until you get just to big.
