Page Appears Blank

On Netscape your page will appear blank if you have any <table> tags without </table> tags. To test if this is your problem, try loading the page Internet Explorer. Internet Explorer tends to forgive these types of mistakes and display the page anyways.

If you're not using tables, still check to see if you have any tags that are missing their closing tags and look for any quotation marks that you might not have closed.


Image not displaying

There should be a pic here -->

This indicates that the browser could not display the picture that you referenced in the code of your web page. This could be caused by one of two things; either the file is not where your HTML code says it is or the file if not viewable. Check the address and file name in the IMG command in your web page to make sure it has the correct name and address. Often people place their images in a different directory that the source code. If that is the case make sure that you include the image directory name in your IMG command. For example:
If my picture, me.jpg, is located in a directory called images,
my IMG command should look like the following:
	<IMG SRC = "images/me.jpg">
If problem isn't in your IMG command make sure that the file permissions are set correctly on the image. To check the permissions on the on the image in my example above try the follow:
 % ls -l images/me.jpg You should see 
  the following: -rw------- 1 yourID student 78 Feb 5 08:58 me.jpg -rw------- 
  would indicate that the read permissions have not been set. -rwxr-xr-x would 
  indicate that the read permissions have been set. To set the permissions correctly
