More About Creating Content
See the terminology section below if you are not familiar with the mnemonics used.

1. Content Format: Web pages are written in HTML code. However there are two other formats which can be displayed - these are PDF and image files. Two of the commonly used image formats are JPEG, or GIF.
2. HTML vs PDF: The format of HTML pages is controlled in part by the user's browser - images are fixed in size but text size and other characteristics are affected by the browser. Both text and images are fixed in PDF files which are viewed in the same browser window as HTML files, but using a viewer provided at no cost by Adobe and which must be installed by the viewer.
3. JPEG vs GIF: JPEG files (file extension is .jpg) are used for photographs and other images where colors and patterns are complex. These image files may be large in size unless they are compressed - this compression can be performed using image processing software (where you determine compromise between appearance and file size). GIF files (file extension is .gif) are used for relatively small, simple buttons and other images where colors and patterns are simple. The file size is usualy small.
4. Text Editors: If you are comfortable using a text editor you can use it to edit HTML pages - usually using the cut-and-paste technique of borrowing from existing code and modifying to suit your latest application.
5. Word Processors: If you are comfortable using a word processor for traditional word processing applications, you may be able to use it to produce web pages. You probably can not use a word processor if it is very old. To see if your word processor is appropriate, look under the "File" menu for an option like "Internet Publisher", or the "Save As" option and then look under "Type" to see if "HTML document" is an option. Your word processor may use slightly different words but the concept usually works. More about creating content with a word processor.
6. Web Page Editors or Web Design Software Packages: If you are comfortable using any of these, continue to use them - you likely do not need advice from me.
