Resize an Image in a Wikipedia article
Go to the 'Edit' tab/box of the article in which you need to display or insert the image.
Use the syntax '{Image:Image name|thumb|caption}' where you want the image to appear. The thumb refers to the width specified already. Typically, 180 pixels is the default size.
Change the thumb-width to the size you want. For example, if you want 120 pixels, type '{Image:Image name|120p|caption}.' The image can only be as large as its original size. You can make it as small as you want.
Use 'frame' in the image syntax to maintain the original size of the image. For example, '{Image:Image name|frame|caption}.'
Specify the width options in your account preferences. Click on 'My Preferences,' the third tab/box on the top of the page.
Click on the 'File' tab/box in the 'My Preferences' page.
Set the size of the thumbnails, either 120, 150, 180, 200, 250 or 300 pixels.
Specify the resolution of the images on the 'Image Description' page. The default sizes of the width and height are 800 or 600 pixels.
Choose from the options listed. There are approximately six preferences listed for the height and width of images.
