After I got the following errors:
! LaTeX Error: Cannot determine size of graphic in filename.jpg (no BoundingBox).
when trying:
\usepackage{graphics}
...
\includegraphics{filename.jpg}
And those errors on a .tex file (a friend gave me):
I found no \citation commands
I found no \bibdata command
I found no \bibstyle command
and several other issues with my latex editors on windows machines, I finally figured out to convert that tex to pdf.
First of all I installed the
miktex latex command line tools. I downloaded basic version here, worked fine.
TexnicCenter and LEd can't manage to edit UTF-8 files. So I needed to stick with texmaker (which works also on linux and mac os). To get utf-8 working there, I switched to Options -> Configure Texmaker and turned Font to utf-8.
After I got those issues with includegraphics tags, I changed the 'fast translation'-key F1 to PdfLatex -> ViewPDF (in options) and: It workes well, even with those images.
