I have a picture and someone wants to blow it up for a christmas gift for someone. I have no clue why as its not that great of a picture but she wants to make it 24x16.
Question is the orginal photo on my computer is
pixel dimensions are
2100x1257
document size is
17.78x10.64cm
resolution 300 pixels.
Now I have no idea how to go about making this file good for her to blow up.

What software/version are you using?
Note that your pixel dimensions are not proportional to 24x16 -- you either have 24x14.5 or 26.75x16 -- something will have to be cropped or you will have to fill in with some blank area.

| Is the original file that big? Or is that what your cropped photo is? If it's a crop do you still have the original that you can work with? |

| I prefer C4 for blowing stuff up. |

You might want to check the terrorist thread and see if you can get it through the pat down.
eta: You would be surprised at what sizes can be printed with just a little effort. Some careful upsizing may get you there.

oh I am so lost. I have Photoshop C4, but I do not know how to use it very well. I got in to photography awhile ago but kinda gave up due to lack of time and understand lol.

You can try this tutorial on resampling
Or ...
ΓΆ€ΒΆ Go to Image > Image Size
ΓΆ€ΒΆ Check that "Resample image" and Constrain proportions" are both checked, use the BiCubic Smoother algorithm
ΓΆ€ΒΆ Enter the critical dimension (24" or 16") in the appropriate box, then enter 150 in the resolution (pixels/inch) box
ΓΆ€ΒΆ Crop/apply borders as necessary
ΓΆ€ΒΆ Choose "SaveAs" to save a new version
ΓΆ€ΒΆ Flatten the image and sharpen as necessary
ΓΆ€ΒΆ Choose "SaveAs" to save the final version while retaining the earlier versions in case there's a problem.
150 pixels/inch should give you decent print quality |

You need to determine the viewing distance. 18cm x 11cm is a relatively small image to view, and I suspect that viewers will scrutinize the shot, if it isn't large. This means that you should be careful not to enlarge too much, but then again,
it depends on the shot. Some photos look charming soft, others do not.
I would start copying the original and enlarge the image in increments of 10% at a time (Image Size/PS), and see, if the image quality is still acceptable after each step. This way you should be able to approach the desired dimension, although not precisely, since the original image ratio has remained unchanged. Beyond that you would have to use interpolation software like Genuine Fractals, which is probably more than want to do here.
