How to make an iPhone photo larger?

So I made a meme from a picture I got off of google, but it is very small. I want to make it my fb profile picture, but it won't let me because it says it's to small… Does anyone know how I can make the photo larger? It's ok if it's blurry I don't mind. Oh yeah and I don't have a computer, I can only operate from my iPhone 4S:/

Iphones are made of inelastic material such as glass and high-grade plastic. It won't change size

As long as you don't mind it being blurrier, then you can enlarge it in almost any image editor. But only on a computer - sorry but you can forget using your phone. Borrow a computer if needs be. Some internet cafés and public libraries have computers with basic image editors you could use.

GIMP is free http://www.gimp.org/...w.gimp.org - just open the image in GIMP using File > Open - navigate to the location of the image file, select it and click Open, then click Image > Scale Image > change the size, click OK. Save the image. Job done.

If it's quite blurry you might be able to improve it a little by clicking Filters > Enhance > Unsharp Mask > OK.
