I use the built-in Slider in 002044. But if I change the example pictures to mine, this occures faults in the pictures or the slide behaviour. Pictures are not overblended fully, you can see the last picture in light transparency behind the new. Seems that the transparent mode (white background is transparent) of my PNGs does not work correctly. I use IrfanView for this. Can you please give me a suggestion what to do?
