My mediawiki thumbnail is weird
From Project:Support desk
After I upload an image to my wiki, the thumbnail turns out to be the same file size as the image I uploaded. For example, I upload image A and A's origin size is "1,024×768". The code becomes "<img src="A.jpg" alt="" width="800" height="600" />". The file size is still the same as A.jpg. In Wikipedia, it seems to be another solution to thumbnail. Take A.jpg for example again. A's origin size is "1,024×768". But the thumbnail code is "<img width="800" height="600" src="800px-A.ipg" alt="">". It means it automatically creates a smaller picture against the origin one. How could my wiki do the same thing like that?
You need either GD or ImageMagick for server-side thumbnailing. See Manual:Image_Administration#Image_thumbnailing.
