Utilizo o MikTex 2.9 e eu TexcNicCenter mas não consigo gerar um arquivo .pdf com inserção de imagens nos formatos jpg, png,
Alguem poderia me dar uma dica?
Veja os comandos básicos, em que estou errando?
That's strange - for me the document works without errors and I get a PDF output. I suggest try removing the .aux file and compile again. Besides that, I just can say the document is ok.
Incomplete log files after compilation with TeXnicCenter (TXC) are one of the symptoms for a well known issues with MiKTeX [1]. Open a command line and try compiling your document from there.
And by the way, it would be very nice if you edit your initial post and rephrase your question in English (the official board language). So others who don't understand Portuguese are able to participate in finding a solution. I only guessed the problem from the course of the discussion.
