Hi,
I am using an external method to load an Image from the harddrive. The external method is as follows:
from email.MIMEImage import MIMEImage ##parameters=filename def getDocument(filename): fname = '/mnt/'+filename; input = open(fname,'r') content = MIMEImage( input.read( ) ) input.close( ) return content
When I try to display the content in the webpage what I actually got is all raw data of the file rather the image. So how can I convert the raw data to be dispalyed as image in the webpage. I am using ZPT to display the web page (image). If its dtml I could have used <dtml-mime> tag is there any equivalent to that in ZPT.
This is not a domain for templating languages like DTML or ZPT. Images are read seperately by the client (get a sniffer like shanes tcpwatch or tcpflow and see whats going on there) So your external method has to set the headers. Unfortunalely you open a huge security hole with your solution and by not reading the python documentation carefully ;) fname = '/mnt/'+filename; <--- if I put a filename like "../etc/passwd" I start to have fun. Ah, and image data for web pages are raw. So you dont need mimeimage alltogether. Just open().read() Again, if you want performance, you should use: from ZPublisher.Iterators import filestream_iterator return filestream_iterator(filenameondisk,'rb') Regards Tino
