Here you can determine how images will be displayed. Images displayed by direct pasting of a URL (if the wiki has it enabled) will not be affected by this setting.
* ''Limit images on image description pages to'': This setting lets you choose how big image previews will be on the Image: pages. If you know what your current screen resolution is you may like to set this to one or two sizes smaller than your own screen. If you have a slow connection (such as dial-up) you may want to limit them to 320x240.
* ''Thumbnail size'': Define how big you want thumbnails to appear. This setting will not affect thumbnails with dimensions determined by an editor, nor can it increase images beyond their original dimensions.
