How do I swap image text in Dreamweaver?

Upload the new image into Dreamweaver and just replace the image that you have in the editor with the new one. You should be able to just highlight that area of script, or click on the image itself and it should give you the option to delete/edit.

Insert> image object> rollover image

code will look something like this:
<td height=“50” align=“center” valign=“top”><a href=”../index.html” onMouseOut=“MM_swapImgRestore()” onMouseOver=“MM_swapImage(‘home-’,’’,‘assets/images/home-y.gif’,1)”><img src=“assets/images/home-n.gif” alt=“home” name=“home-” width=“100” height=“28” border=“0”></a></td>

@anartist nails it, you need a rollover. I think Dreamweaver will build it for you (used to be able to anyway) but I don’t know where it is in the menu ‘cause I don’t have DW anymore.

Thank you!
