Who can recommend me a simple slideshow software that simply shows JPG images in a folder and allows alpha-blending between the slides? I really don't need more than that. The standard Windows 7 photoviewer slideshow feature would be enough if it had the simple alpha blending effect (or any comparable, simple transition effect).
No software that needs to create WMV/AVI/MPG/... movies, instead some ad-hoc software, please.
I tried IrfanView, but for some reason it doesn't get the alpha blending right (may be a bug). Lightroom's Slideshow feature uses too much ressources when sliding through RAW slides.
