A couple of folks are sending you in weird directions that surprise me
because in the absence of more specific information from you, your
question happens to have a single *likely* answer, one that has been
discussed in the HTML groups before.
And, no, it isn't a browser-side problem, even if there is one browser
that happens to get the right answer.
You didn't say what kind of image you're sending. How do you think a
browser knows what kind of image it is receiving, in order to be able to
render it? The answer is that the server sends along a Content-type
header. Web servers are typically configured to send JPEG files as
while GIF files are marked "image/gif", etc.
The server will typically be configured to mark responses generated by
PHP files as "text/html" or some XHTML-related type, depending on the
configuration. If instead you are using a PHP file to generated binary
data, then you need, in your PHP code, to set the content-type
explicitly to the right type for your image. Otherwise the browser has
to guess, making whatever choice it's been programmed to make.
