Hi Byren - Welcome to PSG.  The answer to your question was given at the beginning of this thread:  You can do it, but it won't look as good as if the image started with the larger dimensions and no re-sizing was needed.  Whether or not the quality loss will be acceptable to you, only you can say, but there are differences between up-rez'ing techniques.  For example, trees like fractal up-rezing, whereas graphic designs with hard edges at 0 and 90 degrees like the nearest neighbor method.  So, if it is important, have someone who experienced in such things do it for you.


Assuming that you meant 1380, not 1366 pixels for the new long dimension, or you can crop off a bit of the picture after it's doubled in linear dimensions, then you are increasing the number of pixels by 4 times.  Usually, this means that three out of every 4 pixels in the new (ie, larger) image will be guesses made by the software.  No software can know what all those new pixels should really look like, so it tries to make reasonable guesses.  In the case of up-rez'ing by exactly 2x in the linear dimensions, the number of "guesses" is a bit lower (only 2 out of every 4 px) because of coincidences in the locations of the new pixels, but there's still guess work involved.  


If you can, why don't u post the image and we'll see what we can do with it.
