How to show/hide the image on clicking the hyperlink?
I know this is an older post but it may be useful for those who are looking to show a .NET server side image using jQuery.
You have to use a slightly different logic.
So, $("#<%=myServerimg.ClientID%>").show() will not work if you hid the image using myServerimg.visible = false.
Instead, use the following on server side:
myServerimg.Style.Add("display", "none")
