I noticed that AlternaTIFF was a plugin that your PluginCheck page initially reported not knowing anything about. So I went to their web site <> and, using their tools, uninstalled the earlier version I had and installed the latest version. Now your PluginCheck web site asks me to update it, and when I click on the Update button it takes me to a site to install QuickTime. If you will look at the AlternaTIFF web site you'll see that they tell one about how QuickTime has its own handler for the TIFF files that AlternaTIFF is meant to handle, and that sometimes that QuickTime handler can get in the way of the AlternaTIFF one (which is recommended by, for example, the US Patent and Trademark Office web site). I don't want to install QuickTime, preferring to use the QuickTime Alternative program for the QuickTime file formats, and I certainly don't want it interfering with AlternaTIFF. So, unless you know of some specific problem in the most recent AlternaTIFF (which I would hope you had reported to the makers of AlternaTIFF), you shouldn't complain about that plug in in your PluginCheck web page.

Reproducible: Always

Steps to Reproduce:
1. Install AlternaTIFF (version 1.9.3)
2. Go to
3. Look at results, and then click on the Update button by the AlternaTIFF plugin
Actual Results:  
You'll be taken to the QuickTime installation page.

Expected Results:  
I expected to be taken the AlternaTIFF installation page...or actually since I already had the latest version, I expected to see a green button on the PluginCheck web page.

Feel free to email me (at or call me (at 714-537-6400) if you wish to discuss this further. Or just contact the folks at Medical Informatics
Engineering <> and discuss it with them.

Done: -> websites /
Tested on 2nd. March 2011, the problem still exists. Note that AlternaTIFF is used by one of the leading family history sites in the UK (Origins - ).

AlternaTIFF version:

Further information: see for the product.

Required: Either list the plugin as "Unknown", or include it in the list of supported plugins. It makes no sense at all to send people to Apple's QuickTime site (which doesn't provide the required functionality anyway).
The reason why you're getting referenced to Apple is that the Alternatiff product represents itself as "Quicktime Compatible" in its product name. Why it would do that I'm not sure, as it only renders tiff images, and is not a QT replacement. Because of this, it hits the regex that we use to detect the various iterations of the QuickTime plugins.

I'm not comfortable adding an exclusion for the AlternaTIFF plugin, but will discuss with the dev group.

Thank you for your reply. I've e-mailed AlternaTIFF about the problem and I'll post their reply here when I receive it.

No promises, but I'll ask the decision-makers here if they want to start doing that.

We will probably remove the QuickTime spoofing in the next version. We believe the Google Chrome defect that forced us to do that has since been fixed (and few people use old versions of Chrome).
