why is this jpg image not showing up in IE 7 and 8
Although this article is rather old, it might be of use.
If the JPG image was saved using CMYK instead of RGB it may have trouble displaying. It looks like the older versions of IE (and Firefox) have a problem with this.
I can't see anything wrong with the HTML markup you are referring to, and the missing / at the end of your image is there in the source code.
However this image is massive compared to the size of the image element, which will slow loading time down.
I would recommend you resize the image to 405px * 70px so that it fits in the img element without the browser needing to resize it for you (which will cause distortion).
Your image is too big. IE doesn't show images that are way too big. You should make a copy and scale it down to 405px * 70px and then change your HTML to point to the new image.
Nothing wrong with the HTML. And it shows up on Google Chrome, Firefox.
