Dear WM: I tried to follow the instruction, and it seemed to work all right until the last moment, 

when all six images were seen orderly. 

But please look at the final outcome.

Out of six, four are in supine position with head to the left, meaning 90 degrees counterclockwise, 

one of six is hopelessly inverse with its head pointing toward the center of our good earth, 

and finally the last one, not the least, is fully upright.

How can I prevent this erratic positioning?

Or at least how can I correct them to the right position?

Please help me.

I guess the original pictures were in the wrong rotation (orientation). 

You might have taken the pictures in different camera (or cellphone) angles.

Delete the pictures in wrong rotations and then rotate the #1, #2, #4 to the right 90 degrees

and #3 to the right 180 degrees in your computer.

And then re-upload.

My cameras or cell phones are not smart enough to know how I was holding the lens

whether vertically, horizontally, or upside down.

There is some serious problem with the positioning of images.

No matter how I rotated, the images continue to show the same wrong positions. 

There must be something wrong with my laptop.

I can say that all the images have been normal and legitimate.

At this point, I will keep thinking about the problems and causes.

I just don't know why. Very strange...

When I downloaded your picture and, then, re-uploaded them, they all show OK as you see.

There is nothing wrong with the pictures themselves.

I doubt that your computer is wrong either.

By the way, your pictures are too big (in file size) for our website.

Some of your pictures will take up a space of about 500 webpages of average size.

We can not afford to carry your pictures on our website because they will overload our website.

Dear WM: You have done wonders for me, by solving my day-long problems in a second.

Yes, I didn't realize the huge sizes of the photos, and then immediately reduced them to the acceptable dimensions.

Then they are well suited to our space.

Thank you again.

Have a good night sleep.

We are always in the learning mode because there are so much to learn.

We can never master anything.

Bon Voyage !!

I just got the picture on the website, but it occupies the entire space. 

How can I leave margins?

This is the matter of trial and error since that’s the way I have been learning. 

Regretably I lack the formal education on modern computology and electronics. 

In my high school days I thought I was far, far ahead of the packs, but alas! that was an old story from an old man. 

If that doesn’t occupy the space fully, I would take the lazy guys (meaning the unfitting images) to

the Skype(?) and increase the horizontal dimension to 680, 700, 720 and so on until it fills the space fully.

I still don’t have a mathematical formula for it yet. 

I am in a vacant living room of my son’s Southampton home since last night and use my iPad clumsily.

Once I go to the lake home in upstate and sit in front of my old laptop, I can solve a lot of minor problems in no time, 

but it won’t be before the 21st of this month. In the mean time please bear with slightly malfitting images.

Thank you for your interest, Dr. 온.

You got me wrong. I am learning how to put my picture on this website.

I use my iPad all the time. Yesterday, I succeeded to put it on, but 

it was occupying the space fully not like yours. How do you adjust 

the size of it?

Before you insert the picture on the website, please make sure that the dimensions to be acceptable.

I would try the width to be around 640 px if the picture is rectangular and the width is longer than the height.

And I would try the width to be around 500 px if the width is shorter than the height. 

That’s the beginning, and you might adjust a little bit depending upon how the picture occupies the space.

Doc, our website has webpage space (width) of 1,000 pixels wide.

That's how wide I had set up our webpage a few years ago when I made the website.

Then, I thought 1,000 pixel-width was big enough and still it's not too small yet.

Nowadays our cameras take pictures of minimum 1920 pixels wide (HD dimension) routinely.

Also, our monitor screens have gotten larger to 1920 pixels from the old 640 pixels.

The modern picture size obviously exceeds the size of our (or any other) website by two-fold or more.

I think that's what was happening to your picture.

The remedy is simple. There are two ways of doing the thing.

1. The best way: Resize your picture to fit the website by using photo processing program.

If your picture is larger than 1,000 pixels in width, shrink it to somewhere 800 pixel-wide. 

Then, it will give you 100-pixel free spaces at both right and left margins.

Also, save the picture at about 80-85% of the original resolution.

By reducing the resolution, you can make the size of the file much smaller.

By reducing the size and resolution, you can make the file size from 5 megabytes (5,000,000)

to 100-200 kilobytes (100,000). This is 50-fold reducing and it is good for the websites and webpages.

This will save the space in the website (space=money) and make the picture show up faster (time=money).

Any webmaster (not only me) will recommend you to use the smallest size in your webpages

as long as it does not damage the quality of your webpage pictures.

You do not have to worry about the "height" of the picture as the website can stretch to any height

by simply scrolling up and down.

2. The second best thing: Just add "width" element in your "image" tag.

For example, the original image tag is "<img src=http://xxx.com/yyy.jpg>"

you add width element by "<img src=http://xxx.com/yyy.jpg width="800">"

In this case, if the photo is bigger, the website has to reduce the size to 800 pixel-wide to show it on the screen.

This will take extra time for the processing and website has to keep the unnecessarily large file

wasting a big amount of space (keep 5,000,000 to show 100.000 picture as an example).

I made a quick explanations. If you have any trouble in doing the above, please let me know.
