Introduction

AlternaTIFF is free browser add-on which can display most of the common types of TIFF image files. It is available in two versions: an ActiveX control for Internet Explorer, and a Netscape-style browser plug-in for most other browsers. The plug-in also works in some versions of Internet Explorer. It requires Windows 95/98/ME/NT/2000/XP/etc., and a 32-bit web browser. It is intended to work with Netscape Navigator/Communicator 3.0 and higher, Microsoft Internet Explorer 3.0 and higher, and Opera 3.51 and higher. It may also work with other browsers.

AlternaTIFF was designed primarily to be used for convenient viewing of large (around 200 dpi) black-and-white scanned documents, using a minimum of mouse clicks. However, it should be quite acceptable for other kinds of images.

Installation

AlternaTIFF is available in two forms: a Netscape-style plug-in and an ActiveX control for Internet Explorer.

Installation of Netscape plug-in

The file alternatiff-1_x_x.exe is a self-extracting archive. Upon execution, it displays a dialog with a Setup button. Press the Setup button run the install program.

AlternaTIFF must be registered before it can be used to view images. If you have never registered it before, you will be shown a form to fill out for automatic registration over the internet. This feature requires an active internet connection. (It will attempt to use Internet Explorer's proxy settings, if available.) If your computer does not have a direct internet connection, press the "Manual registration" button to allow you to enter an activation key that can be generated at any time at a web site.

If you are not able to complete the registration at this time, you can still continue with the installation by pressing Cancel. However, the plug-in will not display images until it is registered. Registration can be completed later when the plug-in is in use, or by re-running the install program.

After registration (if necessary), you will see a dialog box that allows you to choose where to install AlternaTIFF. Use the checkboxes to the left of each section to choose whether to install to that location. In most cases, one or more of the Location fields will be filled in automatically. In the unlikely event that the install program was unable to find your browser's plug-ins folder, you can locate it manually by pressing the corresponding "Browse" button. However, that may be an indication of some other problem.

The Associate TIFF images with IE... checkbox tells the install program to reset certain entries in the Windows registry that may be necessary in order to get Microsoft Internet Explorer to find and use this plug-in. It will remove any current TIFF file assocations, and associate TIFF files with Internet Explorer. That means that if you have other applications on your computer that handle TIFF files, they may behave differently until you reconfigure them.

The Add TIFF to IE's "Accept" list checkbox tells the install program to modify an Internet Explorer setting to make it report to web sites that it supports documents of type "image/tiff". This is useful mostly on intranets. Most people should leave this turned off.

Check the Automatically check for new versions checkbox if you would like the plug-in to periodically check to see if a new version of AlternaTIFF is available. This requires an internet connection. This setting can be changed later from the right-click menu.

Installation of ActiveX control

The AlternaTIFF web site may offer a way to automatically install over the web.

Other than that, there is no friendly install procedure available for the ActiveX control. To install, download the alternatiffx-1_x_x.zip file; then create a folder and unzip the contents of the ZIP file into it. Run the "install.bat" script. You should see the message "DllRegisterServer in alttiff.ocx succeeded."

You will be instructed to register the first time you attempt to view a TIFF file, if you have not previously registered either the plug-in or the ActiveX control.

Uninstallation

Uninstallation of Netscape plug-in

To uninstall AlternaTIFF, re-run the setup program (alternatiff-1_x_x.exe). If it displays a registration form, press Cancel. Then press the Uninstall button. (This is not available in very old versions of AlternaTIFF.) Alternatively, you can follow the instructions below.

To disable AlternaTIFF, find the file npzzatif.dll in your Plugins folder and delete it or rename it so it doesn't end with ".dll". To remove it completely from your computer, find your Plugins folder and delete the files "npzzatif.dll" and "alternatiff.html". Delete the keys "HKEY_CURRENT_USER\SOFTWARE\MIE\AlternaTIFF" and "HKEY_LOCAL_MACHINE\SOFTWARE\MIE\AlternaTIFF" from the registry.

Uninstallation of ActiveX control

If you installed the ActiveX control automatically from the AlternaTIFF web site, follow this procedure:

If you "manually" installed the ActiveX control from a ZIP file, run the "uninstall.bat" script to uninstall it. You should see the message "DllUnRegisterServer in alttiff.ocx succeeded." Then, if desired, delete the files you unzipped and the folder you created.

When reporting a possible bug relating to a particular image or images, please include a copy of the text from the About box.

Disclaimer

This program is not intended to encourage the use of the TIFF file format as a standard for image exchange. We wrote AlternaTIFF out of necessity, not because we like TIFF. TIFF is not very portable, and it defeats the purpose of exporting your images if you use a format that is not portable.

If you decide to use TIFF, it is your responsibility to ensure that the programs that you wish to use to view TIFF files can read the TIFF files that you create. Don't just expect that because two programs claim to "support TIFF", that they will be able to read each other's images. That is a reasonable thing to expect with most image formats, but not with TIFF.
