Sadly no they cannot.. but there is a way to make some people see it,
When you export a preset in preset maker (like what ruby was saying) a file becomes created that you can send to your friends or anyone that you want to see you preset.
go to "my computer>(C:) drive>Feralheart>presets"
You should see your preset file there, its not any of the pictures its just simply your username_3.fhp.
for example mine would read: Binks_3.fhp
the number depends on which preset file you used when you drew all the pictures!!
But anyhow youll have to copy that file and use a website like media fire to upload it to, then send your friends the link, when they get your preset file, they past it in:
"my computer>(C:) drive>Feralheart>presets"
then they SHOULD be able to see it!
but if you cant figure it out from this you should look up a guide by a professional. ima newbie lol
p.s. When i started out i thought they were called presents too lol
