[Users] How can remove the existing isos from engine

Hi, I uploaded several isos to engine by engine-iso-uploader. But, I found that there is no tools to remove the iso from engine or there is no option in engine to remove them. Any clue to remove them? Just remove the iso from the directory where iso domain is mapped? I think it is a bit rude to do that. Is there any graceful way to remove them? -- Shu Ming<shuming(a)linux.vnet.ibm.com> IBM China Systems and Technology Laboratory
