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, " " and " " are bogus options, and " " shows up as the caption.

 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: - Make File syntax processing match the specification and documentation
 * - Linter fails to detect a quotation mark after the "upright" number.
 * - Conflicting border/thumb/frame options are not detected as Linter errors
 * - Capitalized versions of valid File options are usually ignored, but are not flagged as Linter bogus file options
 * - LintError bogus-image-options triggers on "Thumbtime"
 * - Image caption ending in "px" is incorrectly detected as a Linter error (To work around a false positive error when "px" is at the end of a caption, add sp after "px". It will add a space, which does not change the displayed caption but which makes the error go away.)

In addition some other supported file options such as link3>Special:MyLanguage/Media Projects|video and multi-page formats (e.g. pdf) are also checked.

Common errors include:


 * Repeated options, e.g.  &rarr;


 * Conflicting alignment options, e.g.  &rarr;
 * Conflicting border/frame/thumb options (not reported as a Linter error; see phab link above), e.g.  &rarr;   (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.  &rarr;


 * Two captions, e.g.  &rarr;


 * A plain number instead of a px value, e.g.  &rarr;


 * Typos in options, e.g.  &rarr;


 * Use of  ,   or   (any unlabeled pixel size) within  tags. To fix, remove   or  </>.  Set pixel dimensions using instructions at <tvar|1></>.
