Your emerald waters 1.1 theme, like boober suggested, has an images folder. You need to copy the emerald-waters-11 folder to your public_html/travelblog/wp-content/themes folder and keep the directory structure intact. That means you should see a public_html/travelblog/wp-content/themes/emerald-waters-11/images folder, which contains 12 files. And your public_html/travelblog/wp-content/themes/emerald-waters-11 folder should show the ../images folder + 18 files.
Another problem you have is that some of your files do not appear to be the right size.
Here’s why I suggest you get a good FTP program. If you get FileZilla (or a similar program) you can check the directory structure and use drag-and-drop to copy files and preserve the directory structure. One thing to be careful of when unzipping & installing themes and plugins. When you unzip your theme, it will unzip to an emerald-waters-11 folder, but there will be another folder below this one, usually with an identical name. This sub-folder with the identical name is the one you need to FTP to your server. Otherwise you will end up with a directory structure that will be:
../wp-content/themes/emerald-waters-11/emerald-waters-11 [WRONG]
../wp-content/themes/emerald-waters-11 [RIGHT]
If you haven’t made changes to your theme, the best place would be to get a basic understanding of folders using a program like FileZilla, delete your theme, and FTP it to the right location. You can select the default theme before doing anything of this so your blog is up and running while you change your theme.
Hope that helps.
