I tried this but didn't work..... for the logo I still see a 'X' there.

 

Why are you using '/Common' before the iFile like /Common/logo.png.

 

Is there any other way to provide reference to the logo? like I don't want to use another 'If' statement. Can it be integrated in one 'if' statement - both Image and HTML?

 

Like if I use only logo IF statement, it works and if I use only HTML IF statement, it works but if I use both together, Image doesn't come up.

 

Any help??
