I don't know what advice the person on the other forum gave but if you take ownership of .bmp and grant Full Control to Users, it should delete.
Right click .bmp and select Permissions...
In that Dialog, selct Advanced button > Owner Tab and you'll get this
Left click your user name to highlight it and place a check in the checkbox, Replace owner on subcontainer and objects > OK
Now you should be back at the initial Permissions Dialog
In that Dialog, Click to highlight Users and place a check mark under Allow for Full Control > OK
Right click .bmp and select Delete
