IMG Mouseover


This allows you to create a simple image mouseover feature by adding properties to an image:

It understands the following attributes which can be added to the HTML:

  • img.class=”mouseover” (activates IMG mouseover for this image)
  • img.oversrc (If specified, this rewrites the image on mouse rollover)
  • img.clicksrc (If specified, this rewrites the image on mouse click)
  • img.noresize (If set, this will make the image have the natural dimensions instead of the dimensions of the original image).
  • a.class=”mouseover” (activates A tag as a controller for another image, when clicked a class “selected” is tacked on)
  • a.for (Should be specified to point to target image. Image must be class mouseover)
  • a.for_link (If specified the ID of a link is replaced with this one)
  • a.src (If specified, the click will replace the image with this)
  • a.oversrc (If specified, the click will replace the image mouse rollover with this)
  • a.clicksrc (If specified, the click will replace the image mouse click with this)

Does what it says on the tin

I usually try to avoid plug-ins that haven’t been updated for ages and/or are unproven with the current version of WordPress, but this plug-in does a simle job very well. This is a very common requirement and yet there are very few plug-ins that offer this service. shard’s article was a Godsend as the documentation is very sparse and you do need to get your hands dirty with the html. Even so, this is much much easier than manually writing html and css to do the job.
