Works now with the standard skin but my image is dimmed, any id why?

AS only tells the skin what image to display.  The actual display of the image is done by the skin.  So that question is best asked in the skin support thread for whatever skin you are using.

Is there any way what version or what image or skin to have a slideshow for music artists on the full screen without dimming and a time of 30/40 sec between the images? I had it before(with older version)  but the slides were to fast, RPI4 ARM Libreelec leia 9.2.8

Your question about the slide timing was already answered.  With the 3.x version of Artist Slideshow there is a setting to control slide timing.  I think the stock Estuary skin shows the image without dimming, but I can't remember for sure.
