Hiya, do this:
1) Save the photoshop files as a GIF (you do this:
File -> Save For Web, a new window pops up, under setting select either JPEG or GIF and click OK) -- assuming you have one big image, like an interface...
2) Open DW
3) Insert a table (
Insert -> Table), I usualy make my table width around 725...
4) Then, do
Insert -> Image, and select the image that you converted...
5) Now this where you slice up the image...if you have a menu on the image (most interfaces have an menu) then in DW, select the hotspot (you can get them from the Properties box, just click on the small white arrow on the lower right) and out of the three types of hotspots select the one that suits your image...
6) If you want the menu buttons, to switch from one image to another, you have to do a rollover image (
Insert -> Interactive Images -> Rollover Image)
7) Now, if you image has a place for the HTML files to load...you can do that a number of ways: one way is to create iFrames and iLayers (that is what I did on my site)...
Take a look at how I did it...the interface was done in PhotShop5.5 and then imported in DW, I created the hotspots on the buttons and created iFrames in the center...
I have not failed; I merely found 100,000 different ways of not succeding...
