Is there a shorter version of the following:
Using ASP.NET MVC, this is in the HTML page
<%= IsTrue ? Html.Image("~/images/myimage.gif") : "" %>
I know I'm only really writing 3 extra characters, just wondering if there is something better.

A:
No there is not, the ? operator is itself a short hand for the if else statement.

The conditional operator can only be used as an expression, while `if` is obviously a statement. One is not short hand for the other as they are conceptually different.

A:
Not for the case you outlined.
If you are doing a null check on A you could write var b = A ?? string.Empty;

This one is handy when passing model to strongly typed partial because if null is provided - partial automagically receives model from view.

A:
It might be acceptable to create html helper:
public static string ImageIf(this HtmlHelper helper, condition, url){
return condition ? helper.Image(url) : "";
}
usage:
<%= Html.ImageIf(IsTrue, "~/images/myimage.gif") %>
