Thank You!!! Alex that did the trick.
This is the theme I purchased: http://themeforest.net/item/photolux-photography-portfolio-wordpress-theme/894193
I have tried the techniques the Theme Document suggested it did not work. I am new with word press so I apologize if I posted in the wrong place.
I am trying to replace the logo and upload the new .PSD but when I upload and update the logo does not appear on my website. Can someone please help on exactly what to do to get the logo to appear in my website.
