If you give us a link to your blog, it will be more easy to help… but can’t you simply replace the image file via ftp?

Hey guys her is my website

https://www.globalvirtualcareers.net

I am building a team of virtual assistants please help me insert the logo.
@wprock Im not sure if it’s a studio press. dont see custom header. All I know it’s a genesis theme. I chose the pictures for the header and someone install everything for me including the 4 photos in the homepage.

this is what the stylesheet under editor looks like as of now:

/***** Image Header – Partial Width ********************/

.header-image #header #title-area {
background: url(images/logo.png) left top no-repeat;
}

.header-image #title-area, .header-image #title-area #title, .header-image #title-area #title a {
display: block;
float: left;
width: 460px;
height: 100px;
margin: 0;
padding: 0;
text-indent: -9999px;
overflow: hidden;
}

.header-image #title-area #description {
display: block;
width: 0;
height: 0;
overflow: hidden;
}

Do I need to upload the logo first to media library and then replace “logo.png” to the reallogo name and extension in the above code? Anybody please.I’m afraid to touch this I might destroy everything.

And I dont know the size to put..
