Images
I want pictures on my website. What should I do?

JPEG (JPG) is a popular file compression format which allows the storage of high quality images in relatively small files. The acronym stands for "Joint Photographic Expert Group". We recommend that you use JPEG files for all your photographs and any art work that requires high color depth.  

 

GIF is a widely used compression format for image files developed by CompuServe. The acronym stands for "Graphic Interchange Format". Since there is considerable loss of color depth in GIF compression, we recommend that you use this format only for line drawings and diagrams requiring only a few different colors (i.e. no graded shadings.)

 

Animated GIF is a file containing a series of GIF (Graphics Interchange Format) images that are displayed in rapid sequence by some Web browsers, giving an animated effect. See also GIF.

FAQ

I try to convert an image to a different format but my program won't let me.
Some formats can't be converted directly to certain other formats. Try converting the image to the "RGB" format (it will be one of the options), then to the format you need.

 

My program won't let me save as a GIF
This can happen if the image has more than 256 colors. You need to change the file mode to "Indexed Color" - consult your program's help file to find out how to do this.

 

When I upload an image to my website it doesn't work.
Assuming your file is a JPG or GIF, the cause is most likely an HTML error in the web page rather than a problem with the image file.

 

How do I save an image from a website?
Go to the web page, right-click the image and select "Save Image As..." (or whatever equivalent option your browser uses). Make sure you have permission to do so - otherwise it's theft.

 

How can I create a snapshot of the display on my computer monitor?
Use your keyboard's "Print Screen" button. This is like taking a photo of the current display on your monitor and copying it to your clipboard. Open your graphics program and create a new file. If necessary, specify the size of the new file as "current clipboard". Then select "Paste" and the snapshot is inserted into the file for you to edit and save. This simple method is how we created the Photoshop 7 screenshots for this tutorial.
Note: If pressing the "Print Screen" key doesn't work, try holding down the "Alt" key while you press "Print Screen".
