Winimage is nice but you have to buy it.
EXE files are... FREE!
That's kinda sleezy.WinImage only needs to be paid for after being used for 30 days.
Winimage has a very nice set of documentation when you download it. Put simply, run WinImage, select File Open to open the image you need, then under the Image menu, select Write. Make sure the correct floppy drive is selected, insert floppy disk in drive, and Press OK. In about 2 minutes, the disk will be created.
That's kinda sleezy.
It's also not correct.
So, what do you use after WinImge stops running for free and you don't want to buy it? You gotta have something that does .IMG files.
