Want to share something, i found useful, about loading gdal generates
tiles
as raster layer in qgis:

this method can be used also to speedup qgis-mapserver rendering
Sounds simple, but the result looks a bit weired. The latest version of
openlayers plugin allows freely all zoom scales, with quit good tile
resizing.
Just discovered two things:
Changing EPSG to 3857 makes the TMS compatible with Openlayers plugin,
looking much better. 900913 and 3857 should be principally the same, but
Qgis makes some reprojection which makes the TMS tiles rather weired in
3857 projects.
And with TMS I can use self-made transparent overlay tiles, setting the
transparency color manually to RGB 0-0-0. Thats the only thing I can not
do with Openlayers plugin at the moment.
HTH,
