Glad you figured out something that worked. For future reference, you might try...

• Use the File Browser tool. If you type Import[, that should automatically create the close brace, so you'll have Import[] with the cursor between the braces. Now type " and it should automatically insert the close quotes, and you'll have Import[""] and also a little tooltip kind of thing that says "File Browser". Click on "File Browser" and you can navigate to the file you want. [I'm using version 14, but this functionality has existed for awhile, although I'm not sure exactly which versions support it.]
• Use FileNameJoin. Rather than try to figure out the directory delimiters and escape characters yourself, let this function build the path name for you. So, some thing like Import[FileNameJoin[{$RootDirectory, "Users", "bob", "Desktop", "the photo.png"}]].
• Use specially defined paths. If the file you want to import is in the same directory as the notebook you're working in, you can do this: Import[FileNameJoin[{NotebookDirectory[], "the photo.png"}]]. There are other defined constants, e.g. $HomeDirectory.
