<IMG> tags work great for static files. And for files in the db that use
the upload field type, the "app/download?obfusctatedfilename" provides a
handy way to download the file. (The usual way of finding
obfuscatedfilename is to do a select() based on the original filename
(which upload fields can also store), or a tag, or the id if you already
have that in hand.) You can also use that url in an <IMG> tag.
In your view,
<IMG src={{=URL("download", "obuscatedfilename")}} />
or
{{=IMG(_src=URL("download", "obuscatedfilename"))}}
If the file in the DB isn't in an upload field, you can use
response.stream(filepath,
request) or set the content type and return the read results, like
Massimo's example in
<URL:https://groups.google.com/d/msg/web2py/iP3vSfKn-8c/UzINycmsBwAJ>.
My previous example,
<URL:https://groups.google.com/d/msg/web2py/MTJoZc1Kh6I/oYjxBn2KCQAJ>
used cStringIO, but it seems that can be skipped especially if it is an
image file.
