Do you mean scaled images?
The current version of TRichView uses Graphic.StretchDraw to display scaled images. This procedure uses a very simple scaling algorithm.
Anti-aliased algorithm is planned for future, but not very soon.

StretchDraw is used automatically.
For example, when image is bitmap, it is loaded in bmp:TBitmap, and bmp.StretchDraw is used to display a scaled image.
Image drawing cannot be changed in the current version.

In future, we plan to generate image thumbnails using advanced scaling procedures. But, as I said, not in very near future.
