This is correct. Your error looks like you used another export filter instead of export -> PDF(pdflatex).
But what happens if you export your file to LaTeX and then process the resulting newfile2.tex manually?:
In a console window change to the folder where the .tex-file is and type
pdflatex newfile2
Also, even without the png file, when I to use the "View/PdfLaTeX" toolbar, I get an error message:- Cannot view file No information for viewing PDF (pdflatex).
You're using LyXWin, right? Then you have to tell LyX a program for that action. Go to edit -> settings -> file formats and choose pdf. Now enter the name of the .exe of your pdf-program in the field viewer. (E.g. if you use acrobat, the name is acrobat.exe, so type in
acrobat
(Adobe Reader has another file name) )
Do this for all three pdf file formats and then restart LyX.
