Hello, I'm new to XAMPP.

I've tried to display some png images in following ways. Some get error some doesn't.

Code: Select all: Error: Firefox message : Image cannot be displayed because it contains error <img src="http://localhost/tools/12345_s.png" alt="abcde"> No error: <img src="./12345_s.png"> No error if directly opened: file:///D:/path/12345_s.png No error if uploaded to 3rd party host online

It only happens in Firefox 3 (disabled all plugins already) & IE8 but not in opera and Google Chrome.
In Opera or Chrome, the png image sometimes appear broken via localhost.
But when I open it directly with firefox or other image software, they look normal.

jpg images work fine.

XAMPP 1.7.3 (same problem in WAMP) on Windows XP SP3
php.ini : memory_limit = 128M

What is the problem?

Well - it might be really useful to see the code that went with the errors.

:shock:

Thanks for the reply!

The code will be nearly the same. Just a simple html img page.

Code: Select all: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <html> <head> <title>Testing</title> </head> <body> <img src="http://localhost/tools/test/8980387_s.png" alt="thumbnail_8980384"> </body> </html>

Here is a sample of the png images that is causing the error

Ahhh - nothing to do with your code or XAMMP.

I'm pretty sure it isn't 'really' a browser problem - its a source image problem, and some browsers are less picky than others. The problem is browsers have different rendering engines, so you get different results. Photoshop 7 had to be patched for this, and there are still png output options that will produce files that don't render on all browsers. As I recall - always select the 24 bit options - I'll look later at home.

Google "png alpha channel problems"

Good Luck, and 'chill a bit' as you are not nuts...
