Well, once again sorry for answering myself, but, as I'm trying to understand this and read posts in Internet I find out more things, for example, that in the official book this is said: "It uses the filename to determine the extension (type) of the file, creates a new temp name for the file (according to web2py upload mechanism) and loads the file content in this new temp file (under the uploads folder unless specified otherwise). It returns the new temp name, which is then stored in the image field of the db.myfile table.", so It's clear to me that it's normal that my image is stored with a strange name, it's its temp name.
This makes me think, is there any way so the stored file is accessed directly via URL, something like http://mysite.com/myapp/uploads/myfilename.jpg?
