Error including image in Latex

Question

I am getting the following error while compiling my Latex File :

! LaTeX Error: Cannot determine size of graphic in tree.jpg (no BoundingBox).

Why do I get this error ? What has this to do with an .eps file ?

In fact, I could compile it fine with MacTex on my machine. But when I submit it online to a scientific journal for publication, it compiles it on the server and sends me the resultant PDF which has all these errors that prevent it from compiling.

I am using the following syntax for including the images :

\begin{figure}[!h]
    \begin{center}
        \scalebox{0.45}{
            \includegraphics{tree.jpg}}
    \end{center}
            \caption{\small A sample}
            \label{tree}
\end{figure}

What should I do ? Could it be that their server is using an old compiler ?

UPDATE : It finally worked. I converted the first image to PDF and the compilation happened perfectly. I guess it used the bounding box value from that PDF and applied it to all images.

Answer 1

To include png and jpg, you need to specify the Bounding Box explicitly.

\includegraphics[bb=0 0 1280 960]{images/some_image.png}

Where 1280 and 960 are respectively width and height.
