Hi Zdenek and all,

A perfectly good way to send schematics and images is using 7+ and it's 
done all the time. It's simply a form of ASCII so any node should support 
it just as it does plain text.

Of course it's foolish to start with a .gif image, it's one huge file, so 
reducing the image size and converting to .jpg which is a compressed file 
is the way to go. Then splitting it into managable parts and sending one 
at a time (one per day or at least one per forwarding cycle) will cause 
no trouble on the network. The parts are compiled when the image is 
complete and may be opened in any appropriate image viewer.

As far as I know a binary file transfer using YAPP will only go 
point-to-point so such files are only stored on the BBS for local users 
to download. Most BBSes no longer support this function in favor of 
better methods such as 7+ and for what it's worth I once got a virus from 
my local BBS back in the old days and ceased the practice immediately.

Speaking of viruses, never fear those .jpg images sent by 7+ since they 
can't support active content. The .zip files I see once in a while are 
another story and should be handled with care since some anti-virus 
software can't scan the contents of zipped files. The way to deal with 
them is unzip them to a temp folder and scan before opening, active 
content is harmless unless you run it.

Yeah, that's how you can test your anti-virus, deliberately put a virus 
in your computer and see if the software can detect it. It won't do any 
harm and you DO remember where you put it so you can always delete it 
when you're done.
