UNSOLVED ImageSlideShow keeping scale

[KlausLadegaard]

Hi

Today I use ImageSlideShow to show images, having big repository of images has proven I need to resize them on the fly

Setting MaxHeight is needed, but then I get some wide pictures that it too wide to text…
Can I somehow get a slide show, within a frame, where resizing happens in scale?

Help some one has solved this or know how to build this enhancement
