I designed my contact form in photoshop cs6, and i have some pretty text areas, where i want to make that users could type in it, when i put it on web. I know that i have to slice something up, but what next? How do i make a working text box in photoshop cs6?
You don't use Photoshop to create a web site. You can use it to create the graphics for a web site.
And possibly before that a mockup of what a web site might look like, to show people.
To make things work you need to create the appropriate HTML and scripting required to give it life and to connect with the web server's resources.
I agree with Noel. A program, like Adobe Dreamweaver, will be able to do what you want. It can use your Image, say as a background, and then allow you to add query tables, etc., to allow for input from Web page viewers.
To bridge the gap between Photoshop and Dreamweaver as Bill suggests, there are quite a few steps involved, and you'll need to take CSS and positioning into account.
It may be a little too thorough for your specific need here, but the company I work for does have a full course on building and launching a website using the Adobe Creative Suite:
It sounds like you have a pretty good idea of what you want visually, though, which a lot of times is half the battle. Best of luck!
