The new Collage Header/Banner should be the exact same dimensions of the current one so I can simply swap out the image file on the web server.
This is my personal blog/website. Several years ago, I posted a website re-design competition here on 99designs. The winning designer used photos I provided to create a wonderful collage header/banner for the website. However, the pictures of my kids have grown out of date as they've grown older and there are new "heroes" of mine that I'd like to include in the collage. Also, the winning designer is no longer on 99designs.
