[Zope] image uploading problems: changing of object type

hi!!! I am facing this situation. I upload images in to a ftp upload enabled folder. My task is to base64 encode the images and put it into another directory. I base64 encode the files using the external method. When i upload it, ZOPE takes the default type as image. Now if i rename the file into a *.dat file, then the encoding works. Now can i change the type of the object from "image" to ordinary "file" from a script python. Please help!! regards, R K ===== with "freedom" comes great responsibilities __________________________________ Do you Yahoo!? New and Improved Yahoo!
