Help:Lint errors/bogus-image-options


The bogus-image-options error is when an image is detected to use a non-existent option. For example in the code [[File:Example.jpg|foo|bar|baz]], "foo" and "bar" are bogus options, and "baz" shows up as the caption.

Help:Images has details on the supported image options, including a few notes about the quirky behavior of some of the parameters.

Known bugs in the Linter bogus file options detection include, but are not limited to:

  • Parent task: task T274382 - Make File syntax processing match the specification and documentation
  • task T335538 - Valid caption "thumb" in italics falsely detected as Linter bogus image option

In addition some other supported file options such as video and multi-page formats (e.g. pdf) are also checked.

Common errors include:

  • Repeated options, e.g. [[File:Example.jpg|thumb|right|thumb]][[File:Example.jpg|thumb|right]]
  • Conflicting alignment options, e.g. [[File:Example.jpg|thumb|right|150px|left]][[File:Example.jpg|thumb|right|150px]]
  • Conflicting border/frame/thumb options (not reported as a Linter error; see phab link above), e.g. [[File:Example.jpg|border|thumb|right|150px]][[File:Example.jpg|thumb|right|150px]] (always remove the "border" option)
  • A manual line break in |alt= or in the caption. (Remove the line break to fix the error.)
  • Blank options, e.g. [[File:Example.jpg|thumb||right]][[File:Example.jpg|thumb|right]]
  • Two captions, e.g. [[File:Example.jpg|thumb|right|Intended alt text|Caption text]][[File:Example.jpg|thumb|right|alt=Intended alt text|Caption text]]
  • A plain number instead of a px value, e.g. [[File:Example.jpg|thumb|right|225|Caption text]][[File:Example.jpg|thumb|right|225px|Caption text]]
  • Typos in options, e.g. [[File:Example.jpg|thumb|fight|Caption text]][[File:Example.jpg|thumb|right|Caption text]]
  • Use of left, right, thumb, or ###px (any unlabeled pixel size) within ‎<gallery>...‎</gallery> tags. To fix, remove left, right, and thumb. Set pixel dimensions for the gallery using instructions at Help:Images .
  • Use of a px value with frame (remove the px value to fix the error).
