Lay Theme Forum

Hi everyone,
On one of my website's page, I put a .png picture of my logo and it's visible on Safari and Firefox but it's not working on Google Chrome.. Does anyone know how to make it appear normally on every platform ? Do I have to turn the .png into another format or is there another way around ? Thank you all :)

I'm also interested in the answer to this problem... Is there any solution that doesn't include going back to an old version?
