Pls. have a look to http://artefacts.atbit1.de (with IE6 or 7, anything is ok with Firefox) This small page demonstrates, how IE 6/7 will render some (dark) pixels of the image into full transparency, if the css opacity is somewhat other than 100% (happens at opacity=0.99 also).The image itself is a JPG w/o transparency at all. - The upper picture resides on a DIV with white background, artefacts are shown if the DIV fades. - The lower picture resides on a DIV with black background, artfefacts are shown also, if the DIV fades (in fact, here we are fading the image itself, thats why the black background hides the transparent pixel holes...). Does anybody have an idea on how to get around these ugly bug ? Using a black background wouldn''t be a real nice idea, so any hint is highly welcome.

Some addition: I found, that some other guys around still have the same problem, look for it e.g. here: http://forum.pixelpost.org/archive/index.php/t-5969.html The pixels rendered to transparency all have the color #02050a (dark, but not black). So, the only solution currently available, would be to not ue the effect with IE or to substitute the color in question... Any other ideas still welcome... detlevv --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

We now found a (partial) solution. It seems, that the ''errneous transparent pixel'' bug appears with true rgb-images (like png or jpg) only. Also its not a safe solution to replace the color #02050a, while at least with jpegs the color will be reintroduced again on saving. Using palettized image formats (like gif) instead, renders the problem to disappear. So, this is not really a universal solution (as apps like foto galleries will maybe not rely on gif), but for certain purposes it seems to work.
