Benjamin, Please be aware that an Erratum was issued on 23 November 1999 that says you do not need to use relative units on raster images. [1] The full text of this erratum is: <blockquote> 5. Relative units and sizing of images. Added: 23 November 1999. Type: Minor Refers to: Checkpoint 3.4 of 5 May 1999 version Description (and correction). The note for Checkpoint 3.3 should say something about the effect of proportional sizing on raster images as follows: "Use relative rather than absolute units in markup language attribute values and style sheet property values. [Priority 2] For example, in CSS, use 'em' or percentage lengths rather than 'pt' or 'cm', which are absolute units. If absolute units are used, validate that the rendered content is usable (refer to the section on validation). For example, do not proportionally size raster images." </blockquote> I do not understand your question about "hot spots." Hot spots are usually regions of images used to define an image map. --wendy [1] http://www.w3.org/WAI/GL/WAI-WEBCONTENT-ERRATA At 05:06 PM 7/28/00 , Benjamin J.
