I have a issue of displaying .png images on web my web page. Other image types excluding .png just work fine. The issue is .png. The web site is located in a sub domain. In the root, a wordpress site is running.
In firebug, I can see a 403 error. But I can assure that I have set 0777 permissions for all images. It couldn't be a permission issue.
Rarely, .pngs are loading. But the second request gives a broken image. I have applied different cache removal techniques including <FilesMatch>
directive in .htaccess, appending version attributes to image link, using # ...etc. But nothing works.
The most complicated point is that when copy & paste the image link in browser it shows the .png. However not within a web page.
Can anybody help me resolve this?
Thanks in advance.
