Hello guy's, 

I want to show uploaded photos and pdf's documments, to users, online

Example, a page show thumbnails of photos uploaded, and when user click on thumbnail, it open a full photo or pdf online

Are you saying that a download request never terminates?   Can you use your browser's developer tools to see what's happening in terms of requests-responses (as shown on the network tab)?

Or are you saying it doesn't display in the page, but goes straight to saving the file?

You might also recognize Antonio's response in the example from Chapter 3 of the web2py book (in image blog):
which also displays the image on the page.

Good luck!

Try this in your view:

def pdf_online():
    response.headers["Content-Type"] = "application/pdf"
   
    return (file=path_to_file)

in template pdf_online.html :
pdf_online.html

:

{{=file}}

Take a look at the book example (has controller and view).  Link is in the edited version of the message you replied to.
(Not sure why the unedited version was still around 2 hours later)

assuming

db.define_table('mytable',Field('myfile','upload'))

and

from = SQLFORM(db.mytable)

and 

record = db.mytable(somenumber)

You can do

{{if record.myfile.endswith('.jpg'):}}
   <img src="{{=URL('download',args=record.myfile)}}"/>
{{else:}}
   <a href="{{=URL('download',args=record.myfile)}}">download</a>
{{pass}}
