You probably have to stream the object in the response.
def getmyblob():
import cStringIO
import os, shutil
# print request
if len(request.args) == 0 or not request.args[0]:
raise HTTP(404, "unknown file not found")
row = db(db.mypics.pname == request.args[0]).select().first()
blob = db[somethingsomething].[copyblobltotmpfile]
dst = os.path.join(request.env.web2py_path, "application", blob.tmpname)
if not os.access(dst, os.F_OK):
print dst
raise HTTP(404,"funny, that's not here")
imstat = os.stat(dst) filedata=open(dst,"rb").read()
response.headers['Content-Type']='image/jpeg'
response.headers['Content-Length']=imstat.st_size
return response.stream(cStringIO.StringIO(filedata))
Then your IMG tag looks like
<IMG src="getmyblob/{{=blobrowid}} alt="image file for {{=blobrowid"}}
title="={{blobrowid}}">
Sorry for the hacky look of this, I don't have much experience handling
blobs; the code I use is for an image as an ordinary file in the
filesystem. (My app tags pictures transferred from my camera.)
The field type "upload", combined with the default/user/download()
function, hides much of this from you, but has something similar under the
hood.
Good luck!
