Help:Lint errors/bogus-image-options

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

Some of the known bugs in the Linter bogus file options detection are mentioned in, but not limited to:

• Parent task: task T274382 - Make File syntax processing match the specification and documentation

Some other supported file types 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]]
• 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 ###px, left, right, 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).
• Use of pxpx in a size value (remove the extra "px" to fix the error).
