Janeks -

It might depend a bit on your usage model, but TIFF is certainly a very
good choice, and JPEG is a very poor choice.  It's not so much a matter
of compression (TIFF images can, optionally, be compressed, too) but the
style of compression JPEG uses.  You need to do a lot of decoding to get
just one pixel out of a JPEG image, and that is not the case for TIFF
images.

Hi, List!

Currently I have background layer in JPG format.
In ArcView TIFF format works faster (because uncompressed) will it be so
for
MapServer?
And which is the best format?
