[SOLVED] How can I insert a picture in a custom page template?

Hy guys! I've stumbled into this problem.... I am trying to insert a small image in a homepage template I did, but it just doesn't seem to show...

First thing I tried was to insert it inside the custom homepage.php file (copy of index.php with some little modifications), but I couldn't get it to show (I tried with img src and almost all other options I could find reading documentation).
I also realised that I could include it inside the loop (although I'd rather not).I went to ATO -> Style and edit center column -> Content inside loop and tried to insert it there. Still nothing. Anyone can give me an idea what am I doing wrong? Or what/where to search for more information?

Thank you!

I am running WP on a localhost trying to play arround and learn so the page it's not online.
