white pixels in JPG image while fading (Slide Show) in Internet Explorer

A very curious error that I have noticed recently in our Slide Show / Slide Show: As soon as images (JPG) with really black areas are present (RGB: 0/0/0) are see this during the slide (transparency blending) as transparent.

causes of bright dots on black faces in the picture, what stands out very well then, especially not when the transition period lasts a little longer. It is interesting that it "only" Internet Explorer is concerned, Firefox is also clear it.

Corrupt image with white pixels	correct image after the fix

solution:

This bug is clearly attributable to the browser, Internet Explorer, not a bad example of the export graphics program itself. Also, the JPG image itself has no such bright areas in these areas.

order for this error can be corrected, you have to adjust, unfortunately, the picture itself in the graphics program. In my case this was in Photoshop estimated as follows:

 Photoshop: 
 image -> Customize ... -> Levels 
 -> then reduce the black slider (Slider) below at 
 tonal range to about 2-4 points. 
 then export the image again and save.
