What's the best Raster type to use as reference

[Anonymous]

I had 24 tiff images that were around 140 meg apiece. I converted them
to jpeg files that were reduced to about 5 meg. So far, so good.
Viewing these raster images showed plenty enough detail. But only after
inserting 5 of them together, I run into memory problems.
I'm working with NT and 260 meg of RAM, all of which I've given to the
/temp directory and have changed the file paging to handle 5 times that
amount.
And yet, Acad's telling me I need like 219140KB for my next mapiinsert!
Now these jpeg files are not near that large.
What gives?

MrSid is very compact. This is supported with AutoCAD MAP R5, or you can use
CAD Overlay.

Jpgs are a storage compression, and are uncompressed when they opened. You
can see this when you insert a jpg into MS Word and save it. The resulting
file will be much larger than the original jpg.
