Cant move screenshot pics to trash, error code -36

I have 5 screenshots that I have on my desktop, I have tried several times of moving them into the trash to delete but am getting the -36 error code, "The Finder can't complete the operation because some data can't be read or written. I ave tried dragging the files into dot_clean but it says invalid directory. I have also checked the permissions as I am the admin for the computer.....any suggestions....super annoying I can't just delete some pics off the desktop screen....
