<dd>Rollovers are very easy using Dreamweaver. All you need to do is export two images from Fireworks (the image itself and the rollover image). Next, in Dreamweaver, click on Insert>Rollover Image. Give a name to the image, choose the images from the folder icon and finally give the link to the image. That's it! You've now got a great looking effect for your site.

<dd>Before uploading your site you need to make sure that there are no dead links in the site. You can do this by going to your site map, right clicking on any of the files and then clicking on 'check links'. Now you can choose to either check links in the entire site or within the selected file or folder. If there are any dead links you can fix them by using the folder icon to select the right files.

<dd>After resizing an image in Dreamweaver, click on Commands>Optimize Image in Fireworks. You will get a dialog box saying 'Editing image.gif. Do you wish to use an existing Fireworks document as the source of image.gif.' Click on No and then click Update. The image is now updated and optimized in Dreamweaver. This saves you the trouble of opening the image in Fireworks, resizing it and exporting it again.
