If I made a design as a single jpg picture would i able to edit it with dreamweaver or would I have to take it apart with photoshop?

You'll have to take it apart.

The proper way would be to splice it with photoshop if your going to make a full site. If your making some type of splash page, you can make links on the image without cutting it up.

thanks. ive made a few sites with a wysiwyg builder. Im trying to make a webhosting template even though im bad at design. Ill higher someone if it fails

You can create a page with the same pixel dimensions as the photography, then set padding, margins to zero, and no border. Then you'd only have a photography coming up.
If I don't misinterpret you, you only want the image to show when someone navigates to your site's address?

You could simply pay to have it sliced and coded. There's a lot of offers in the advert forums you may consider to be quite reasonable considering how much time you could spend trying to do it yourself.

Im going to slice it up with gimp now. After using gimp I found I could design sites about 3 times faster and its a FREE program.it also slices the design for you. I will code it myself though which wont be a big deal thanks everyone. I could do the lazy way and just add clickable writing but that wouldnt work out for some people's enjoyment

Better, use photoshop "slices" for images. And CSS modeling. Photoshop has a function to make a html document that includes cropped images. You may use the html code for measuring the images width and height. It'll be quickly than use photoshop's tools.

see if the gimp has image mapping...makes links out of your photo

Also, one big image is downloading slowly then some little. It happens, because a browser try to download some different images together from all of active sites. Bacause, if your site has more images, they will be downloaded quickly than one big.

Use the slicing tool to slice up individuals parts. Or you can just map your links.

photoshop is one of the best tool to edit and slice images..

No one used firework? I feel it is more convenient than photoshop.

I say gimp if you dont have photoshop, but only if your using this to learn. If you want something good hire a professional!

photoshop is a very good software to edit and save all type of images

Actually Photoshop is EVERYTHING one may need to work with images :-)
