welcome here in the Winamp & SHOUTcast Forums.
At first I want to leave a link to another thread in German, "bilder in presets einfügen":
if You want to try out also the 185 DLG Presets which work with random textures.
I have written my image-file-naming-rules for random textures and desktop wallpapers, You can read more about them in my thread "My Photos of Parks in Berlin 2016":
Some more tutorials and download-links to my own works can be found in my Devious Journal "Winamp forever - Music forever!!!":
And I want to leave also my slideshow-playlists with the latest update from 17th January 2017. I have another USB-Stick at the computer in the meeting-point now, because I am doing some updates on Mediafire, so that this time my attachment has no date.
Currently I myself have over 10100 presets and over 4400 textures on my PC and notebook in use, and I use the extended versions of my collections with textures and wallpapers which are much bigger than the official versions...
