Thank you for reporting the issue. I will look into it and try to find out what
caused the issue.

I should have mentioned that I was using a png file. Happy to help fixing the
problem, but I wasn't sure where to start :)

Hi,
I get the exact same problem with .jpg and .gif-images, regardless if I am 
generating
a TeX test, TeX file or trying to generate a pdf.
It seems that the image handling is a bit broken.

Thanks for a terrific extension. 
The possibilites are endless, to use a movie quote. :-)

Btw, .gif images doesn't seem to be visible in 0.92 either.

Oh,sorry!

.gif is not supported by pdfLaTeX, so that's not wiki2LaTeX's fault.

But now I am looking  at vector images for use for logos, and stuff like that. 
.svg aren't supported by pdfLaTeX, byt .eps files are, AFAIK, and they don't 
show up
in pdf:s generated by wiki2LaTeX. Which I suppose that they should?

On the other hand, .eps:s don't show in the wiki anyway. 
It would just be great if there was a way to get vector graphics into wikimedia,
through wiki2LaTeX and into .pdf.

That's one of the main issues regarding image-support: Images work totally 
different
on LaTeX (including file formats) compared to Mediawiki.

So the only way would be to include some converters. An SVG to EPS converter 
would be
great, as well as a Gif to JPEG converter.

But the issue here is a failing API Call to Mediawiki. I hope to be able to 
look into
it the next few days.

The problim is in this part of the code ($link variable is undefined):

            case NS_IMAGE:
                $parts = explode("|", $link);
                $imagename = array_shift($parts);
                $case_imagename = $imagename;
                // still need to remove the Namespace:
                $tmp_name = explode(':', $imagename, 2);
                $imagename = $tmp_name[1];

FIX: replace "$parts = explode("|", $link);" with "$parts = explode("|", 
$link_int);"
