AlternaTIFF is a web browser add-on (ActiveX control or plug-in) that displays most of the common types of TIFF image files. It works in most web browsers for Windows XP and higher (Vista, 7, etc.).
Don’t know you, but in our Institute we had some issues visualizing documents uploaded on the Protocollo Informatico web portal of CNR.
After having contacted the technical support of the service we had instructions to install this alternaTIFF software on our system. Given that our dedicated machine to this activity is a Windows XP box, and the fact that you have to use Internet Explorer 8 to make the Protocollo work properly, I had no chance but to follow the authors’ instruction to finally solve the issue for our administrative staffers.
