Red X appears over PNGs in IE

I've got this web site written in ASP/C#, and when I display images through ASP code like:

<img src="images/someImg.png" id="Img1" alt="" align="top" border="0" width="295" height="35" style="position:absolute;left:327px; top:545px; width:295px;height:35px;z-index:11" /> 

The problem is, in every other browser the page looks perfect, but in IE, images are displayed and on top of them there is the little red X which is shown when the picture is missing. The picture is obviously not missing because it is shown in every browser, but in IE it is shown and there is the "missing picture" X on top of it.

Most solutions on the web suggest adding a "./image/..." or "~/image/..." but I've tried it and it doesn't work.

Also, when I display images from a database in any kind of default ASP.net data viewer (e.g. DetailsView) some of the pictures are shown normally, some with the little X on top. Again, this is only in IE, an开发者_开发问答d only with images with .png extension. In every other browser it looks fine. I even got the page validated and it works perfectly.

Does anybody know a solution?

I tried a couple of PNG fixes I could find and still nothing.

PS: I'm currently running the page locally. Could this be a problem?

Here is the link I found the solution
