The optional named parameter size will override the default height of the icon (between 10 and 20 pixels):

The value for size must be an integer and should not be any larger than the display height of the diagram icons themselves (20 pixels in most diagrams).

The icons' wikilink and alternate text can be overridden by adding the optional parameters |link=newlink and |alt=othertext. Note that if only the |link= parameter is changed then the |alt= parameter will change from the default to the new link text. (However, the |alt= parameter can be changed without affecting the link target.)

In prose

Please avoid adding these icons within the prose of articles: per Wikipedia's Manual of Style for icons, "Icons should not be used in the article body... This breaks up the continuity of the text, distracting the reader".

In addition, icons used in this way are primarily decorative, e.g. "aesthetics are in the eye of the beholder: one reader's harmless decoration may be another reader's distraction": While the icons provide visual cues in certain circumstances, writing in prose will usually suffice. Instead, provide a link to the services directly.
