Sure you can do it. Define your variable in a file that is included in all your files (like the config.asp is included in all the files). Then your img tag would look like this, using Response.Write:Response.Write "<img src=""" & variable & "/image.gif"" alt=""my image"" width=""100"" height=""50"">"
Using html and asp:<img src="<%= variable %>/image.gif" alt="my image" width="100" height="50">
