Delete Operation but pic not in Trash

[xnsee]

Unfortunately I deleted some pic's, but I did't found the deleted pics in the trash.
In Option "delete to trash" is activated.
Trash is not deflated, some older files are inside.
I found only the link to the pics in the "recent files" option.
I also did't found the pics in a temp-directory.
OS is win xp. I'm not a pc-newbie.
thx for help.
