You have to have web space to put pictures on, send me the pic and I'll upload it for you if you don't have a host. Or you could easily go to http://www.geocities.com
or some place like that to get free web hosting.
My e-mail is firstname.lastname@example.org
if you want me to upload it for you.
Another thing, if you have a layer in photoshop that you want to hide(if this is what you are talking about)all you have to do is, go under the layers control panel and click the eye to hide the layer.
Or do you mean make parts of your picture transparent in your program? (I'm confused, heh)
I am the very disease you pretend to be.
