You set the terminal to png. OK.

Then you call file2.txt, which contains the following

So you open a file 'name.png', but do not write anything to it.
Then you immediately open a different file 'name2.png', which
closes the first, empty, file. Later you plot something.
After the plot you have an empty file 'name.png', and a 
file 'name2.png' containing a single plot.
