------------------------  DIVIDE BY 8 RULE [Image height corrections]

Make sure that your image height is a value that is divided evenly by 8.  The "Divide by 8 Rule"

For example:  Say you image height is 602 pixels high / 8  returns with a value that is 75.25 or not a whole number. Resize your image. However, an image height of 600 pixels high / 8 returns a value of 75 or a whole number. 

Here are a few image height values: 600, 592, 584, 576, 568, 560, 552, 544, 536, 528, 520, 512, 504, 496, 488, 480 and 472

--------------------------- INITIALVIEW <parameter

This is another way to fix this.  Bruce suggests placing this param code into your param command listing on your html page and it will stop the flickering. 

If your panorama is only 180 degrees the initialview must be under this or you will get flickering. The syntax is

<param name=initialview value="0, 180, 60"> for  360 panoramas
<param name=initialview value="0, 90, 60">  for partial panorama

Change the 180 according to your pano horizontal feild of view. Say try 90 . It is not recommended to alter or change the VRML code in the .ivr file.  What to change the value to:  Bruce suggest the following:

• "The only way to do it is look at your pano, say ok, that's about 120 degrees,
• set the initialview to a desirable spot in that 120 degrees. Don't know if
• fractions work, but do you really need to go that fine?"
