"Unknown" bronze cannon

[cannonmn]

A friend says this bronze 4 ?  pounder in a museum in Leipzig, Germany, is "unknown" but the museum seems to have a description of it as French, however I'm pretty sure it isn't.  I can't see much in the little photo.  I should be able to click on it to get a larger one but it is a PHP image, and my 'puter doesn't know what to open the file with.  I looked on web and it advises "notepad" but that results in several pages of pure gibberish.
 
How can we view the larger image, please?

Thanks for the help.  Those pix seem a bit blurrier than the orig on that site, and I was hoping I could find a way to bring up the larger photo that seems to be offered when you click on the small pic on that webpage. 
Anyone offer an explanation of how that all works on the museum's webpage?  I like the larger pix just posted here but the clarity seems degraded and I can't see the marks as well as I need to.

They don"t want you hijacking the picture and posting it without permission on some other website, like here.

Try this link: http://museum.zib.de/sgml_internet/img.php?img=mi000376&width=600 and  play around with the "width=600" part of the URL. 2000 was as high as I could get it to go, but it's still fairly blurry.

That's not entirely true, in certain situations you can use copyrighted work without the owners permission due to the fair use doctrine. I don't pretend to fully understand when it's ok to do so, so the safest bet is to just post a link to the specific image.

I use Firefox and clicking the image on the catalog page gives me the larger image with the title img.php but it is a jpg as a file.  Click on that image and Save As onto your computer, changing the suffix to jpg as you save it.  Then view it directly on your computer.  The larger image is only 600 x 194 pixels so enlarging it is not going to get you greater sharpness.
