The second method is to use an add on program like 'TimThumb' that makes thumbnails from the images and then sends the thumbnails to your computer. Your computer then caches them so after the first time they are instantly there. The problem is that it takes time for the web server to shrink the images down so a cache of images is maintained on the server as well.
I have a third solution that works very fast. When pictures are uploaded to WordPress it sets them up with three sizes, large, medium, and small. They are 600x600 pixels, 300x300 pixels, and 150x150 pixels. They are identified by 600x600, 300x300, or 150x150 being added on to the end of the pictures name. You select the size that you want to use for your article.
Now notice that the 150x150 size is 1/16 the total size of the full 600x600 sized image. Why not just select the 150x150 image, send that as the thumbnail and have your browser shrink it to 100x100 or whatever thumbnail size that you want? The images could then be selected totally automatically and sent with very little work by the web page server. All the work would then be done by the user's computer and that would be very little work they would have to do.
The program would find the image reference in the post, then strip off the last 4 characters (usually '.jpg') then add '-150x150' on the end, then put back the last 4 characters. It sounds simple but it is only about 90% successful so far. The problems are that if the image was smaller than 150x150 to begin with then there is no 150x150 image, so it would have to go back to the original image. The next problem is that if you selected the 300x300 image. In that case the last 7 characters would have to be stripped off before the 150x150 was added onto the end.
Sorry the code listing here on BlogSpot is not turning out well. The code goes in the functions as a replacement for get_the_image that uses timthumb. In live testing this code is about 2 times faster using a database of about 500 items. However about 5 % of the thumbnails did not work, so thumbnails had to be manually created and uploaded to fix that problem. One last change fixed problems where the .JPG was capitalized in the uploaded image but was lower case in the thumbnails.

//GET-POST-IMAGE1 quicker than the script by Tim McDaniels
function get_post_image1 ($post_id=0, $width=0, $height=0, $img_script='') {

I tried posting the code as a gif, but it was too small to read. Thanks to makeblogpopular.blogspot.com I now have readable code!
So I rebuilt the power supply using the schematic of the other 5 KV supply. This time I used a resistor to limit the charge current and to protect the diodes during discharge. The schematic is shown below.
To pull this off you will need a USB floppy drive and driver files from Intel or Gateway. During boot up press F10 for boot selection, select the CD ROM, press enter. Then press enter when is says press any key to boot from the CD. Next press F6 when the option to load SCSI drivers comes up.
When the Bible school started in Tomale we bought a used TV for about $120 for them to use. On this trip I brought a Viewsonic Projector for them to use. The projector can be moved around on a motorcycle when a TV cannot be moved on a motorcycle, well it can be and would be but the long term survive ability of TVs on motorcycles is not good.
Here is another picture showing some of the lighting effects. Those vertical bars are some sort of LED screen that works together like a big TV screen.
The best solution is to replace the capacitors with some non-electrolytic 'paper' types. I used some .47 uF at 400 volt capacitors. These capacitors are much more durable, they are used in Tesla coils because they can take a lot of abuse. If you look at the holes and the drawing on the board you will see that this was an option back when they designed the TV. The picture below shows the new caps soldered in place.
With the improvement the picture is back up and brighter than it had been. The dark area in the middle was caused by the lights being dim from the capacitors being bad. When the light bulbs are dim the light does not reach the center of the screen very well.
