I'm not sure what's going on, but it just happens in this website and just with PNGs.

They start loading but then POOF!, they disappear. I have to check the source code and copy their url in order to see it.

This is happening both in the forums and in the rest of the website, and it started about two/three weeks ago, I think. Not a clue of what's going on yet, but I'm studying the source code to see if notice anything;

Oh yeah, it seems to be an Opera-only issue as well. Damn. [ I refuse to change browser, so don't even dare to use the "get firefox" routine ]

What a noticed:

The part of the code that makes the galleries come out as a huge clump, without any CRLF in the whole thing. Maybe Opera is unable to read these properly (still, why just pngs?). Maybe this happened after you (sedge) changed the links to the icons from "pixels/pixels/icons/icon_###" (or whatever) to ###.html.

Gotta see what's wrong with the forum yet.

We added a PNG transparency script for IE that might be conflicting with Opera. I'll look into it.

Oh, I see. I know sh*t of js, as of yet, but I tried to instinctively fix the code adding a little if: 


// Correctly handle PNG transparency in Win IE 5.5 or higher.

// http://homepage.ntlworld.com/bobosola. Updated 02-March-2004



function correctPNG() 

   if (navigator.userAgent.toLowerCase() == "microsoft internet explorer") {

   {

   for(var i=0; i<document.images.length; i++)

  {

  var img = document.images

  var imgName = img.src.toUpperCase()

  if (imgName.substring(imgName.length-3, imgName.length) == "PNG")

 {

 var imgID = (img.id) ? "id='" + img.id + "' " : ""

 var imgClass = (img.className) ? "class='" + img.className + "' " : ""

 var imgTitle = (img.title) ? "title='" + img.title + "' " : "title='" + img.alt + "' "

 var imgStyle = "display:inline-block;" + img.style.cssText 

 if (img.align == "left") imgStyle = "float:left;" + imgStyle

 if (img.align == "right") imgStyle = "float:right;" + imgStyle

 if (img.parentElement.href) imgStyle = "cursor:hand;" + imgStyle

 var strNewHTML = "<span " + imgID + imgClass + imgTitle

 + " style=\"" + "width:" + img.width + "px; height:" + img.height + "px;" + imgStyle + ";"

 + "filter:progid:DXImageTransform.Microsoft.AlphaImageLoader"

 + "(src=\'" + img.src + "\', sizingMethod='scale');\"></span>" 

 img.outerHTML = strNewHTML

 i = i-1

 }

  }

   }

   }

window.attachEvent("onload", correctPNG);


Make a little test.

Yeah... we have a browser check on every page (dom.js) so the last line is the only thing that changes...

if(oBw.ie){window.attachEvent("onload", correctPNG);}

Well, okay then. That'll probably fix it.

Nope. Didn't seem to have worked. :|

Bleh, I gotta learn this JS stuff.
