What am I doing wrong...? (uploading header/banner)

[WoodChuck'r]

Here's part of (what I think might be) the problem -

I use the FTP to upload the image, and it uploads to it's own folder in the file manager. Whenever I try to move the file to the /images/misc folder, it "looks" like it goes there because the selected file disappears as if it was moved. But when I go to the /images/misc folder the file isn't in there. When I try to search in the file manager to find out where it went, nothing comes up as if the file was never uploaded.
