Technical Support / URL Questions

Stuart and I have found, to date, 777 people who have been serving on USS Concord since Feb 1891. Because the list is so large, we have had to split it into several pieces in order to be manageable. We would like to paste in links to a Table of Contents. Fairly easy to do with the [URL[[/url] code, but unlike [a href=] [/a] the URL notation does not keep us on the same page when we specify an internal link: that is when we click on the link we get a new tab. Is there a way to code the URL command so that we don't keep getting new pages each time we click on the link?

Here is what we tried;

The Logs and FAQ / Making a log easier to read with irfanview
« on: February 03, 2012, 02:39:34 am »
Sometimes you can really improve the legibility of a log page by doing some simple image processing. I have been using irfanview for many years, and it is ideal for helping clean up a page. The source can be easily downloaded from  You can read about irfanview here: 

When I am planning to process some old weather log pages, I start irfanview. Then, once I have a log page up, I copy the image and paste it into irfanview.  The command Ctrl-H will expand the image to its original size. I then enter +++ to expand it even more. Finally, Shift-U will adjust the colour so the page appears whiter and the text a little darker. With each new log page, I just paste the new image into irfanview and it overwrites the old one. There is no need to open and close it each time. In fact, if you use Ctrl-V for the paste command, then the sequence is really fast:
Ctrl-VH  Shift +++U

I hope you find this as helpful as I do.


It is a much easier process than some others I have seen described.
