@aesteban : we have to filter too (HTML or not ?) survey title : because sometimes, some user add
or <img> to survey title.

@DenisChenu: I took a look at this bug. We can fix it if we initialize $tcpdf['base_url'] to a non empty value in config/tcpdf.php but an exception is thrown in /var/www/limesurvey/application/third_party/tcpdf/tcpdf.php(2933) because the image doesn't exist (tcpdf is configured to throw exceptions). In fact, I think K_PATH_URL is useless for LimeSurvey. K_PATH_URL is usefull only if the survey creator write an image whose path contains http://yourhost.com/limesurvey/application/third_party/tcpdf/ and the only advantage is that tcpdf take image from file system instead of using curl.

So, in my opinion, we could initialize

$tcpdf['base_url'] = 'dummy'

or just do nothing. What do you think Denis?

@DenisChenu: I have reproduced the "strpos(): Empty needle" with found images so I think I will initialize $tcpdf['base_url'] = 'dummy'.

Retarding survey title, I think HTML is better than plain text.

I let you go for title HTML ;)

For the image : it can be great if image is taken from system (if able), but deactivate it : why not :)
