Category:Pages using infoboxes with thumbnail images

Taken from en:WP:INFOBOXIMAGE
When adding an image to an infobox, thumbnails should NOT be used. Infobox templates should implement the InfoboxImage module to help with formatting of images so simply supplying the file name will work. For example, to use File:Image PlaceHolder.png, you can simply use |image=Image PlaceHolder.png. Captions should be specified with the |caption= parameter. Every infobox is different and the documentation for the infobox in question should be consulted for the proper parameters to match the image and caption. If InfoboxImage is not yet fully implemented in the infobox you are using, the same alt=, upright=, title=, etc., parameters may be called using Extended image syntax, calling frameless, not thumb.
To fix

Don't use the full image syntax:

|image=[[File:SomeImage.jpg|thumb|Some image caption]]

Instead just supply the name of the image. So in this case you can simply do:

|image=SomeImage.jpg

and optionally:

|caption=Some image caption.
