Abraham, you will need to edit join_index.html file.

This is custom code modification and you are doing it at your own risk. Note that all custom changes will be erased if you update the software. So if you are changing source code, keep track of what and where you are changing.

I've been trying this for about an hour now and no luck. Can anyone provide any tips?

Thanks

Eric, which theme are you using?

Hi Aliia,

Thanks...By the way in which specific line we can add the code. For example in the theme blueline in which we want to add some image on the sidebar..

Thanks,
Abraham

Abraham,  unfortunately I can't tell which line you should edit.
