If you really don't want to download Stuffplug NG another way you could do it is to get the
CE/DP Backup wizard to save your emoticons to a folder, then rather than putting them onto a floppy you could right click on the folder with your saved emoticons and select send to> compressed zip folder, you can then upload the compressed folder to a free file hosting site such as
savefile then note down the link you get at the end of the upload so when you get home you can just type the address into your address bar and download your saved emoticons.
