If you want to chop up a photo and load it in little pieces on the same page:
Lets pretend you have a 1000x1000 pixel image and you want it to load in 4 pieces:
1) Get a photo editor, and cut the image into four separate, and equal sized pieces.
2) In HTML, or WYSIWIG, make a table that has 2 rows, 2 columns.
3) Make the width of the table 1000 pixels, and the height of the table 1000 pixels
4) Make each TR tag set to 250 pixels, and make each TD tag to 250 pixels.
5) Set padding, margins, and frame borders to Zero
6) Between each TD and /TD tag start putting in your chopped up image. In order, you put in the Top Left piece, then Top Right, Bottom Left, then Bottom Right. Each piece goes in a separate TD /TD pair.
7) Save Reload

ALTERNATIVES
You can also look for "free web templates" on google or another search engine. Templates are models you build your site on. Someone designs the site, you add the content. It is a really good way to learn HTML, becaue it is a full site and you can edit it and customize it to the way you want it.
Stealing another sites layout - You can do it, but don't make an exact copy. Don't do corporate sites. Make sure you change it in a major way.

POSTING
If you like, you can post a link to the html (it doesn't have to be complete, just have it posted on a free server or the companies site). There are enough webmasters on this site that you will get plenty of help and design ideas
good luck
