Also note that a file uploaded to an upload field is not stored with the 
name the user passed to the upload form; instead, it is stored with a 
mangled, er, obfuscated name, and to find the file you should expect to do 
a db query.  See Chapter 6 under Field Types.

How are you generating the URL for showarticle()?

Also, I think you can just do an ordinary file open(), rather than having 
to import PIL and doing an Image.open()

BTW, I handle images as  tags, where src=showimg(id), and showimg() 
reads the file.  I also have an example, maybe previously posted, where I 
use download() instead of a custom showimg(),so the controller does a 
select on the upload table, and then
return dict(img=row.fdata)

and the view has
{{=IMG(_src=(URL"download", img), _alt="test image")}}

Good luck!

But I did upload and the image is in the folder.
