Adobe Dreamweaver is a commonly used website authoring tool in the webdesign industry and the recommended HTML editor for the VET VCE IDM course.
I love DW and use it exclusively for HTML sites but for clients, I almost always go with WordPress now. I like creating websites that clients can learn to master on their own without too much trouble. This gives them the option of not being married to a designer or web company.
IrfanView is the name of the image manipulation software that was recommended at the VITTA Dreamweaver seminar at Strathcona on the 14th May. Looks like it is only for Windows users.
