Overview

Images embedded into a Daisy Page display full size in editing, but when they are saved, the display as a preview, with a link "Click to enlarge".   

The default Daisy installation only displays full size images if the width is under a default value (at time of writing this was 650px).  If the images is larger, it displays a preview with the "Click to enlarge" link.   

This behavior is defined in the document-to-html.xsl, and can be overwritten in the skin

Basically, we are creating a new document-to-html.xsl inside the skin and changing the Maximium width value.   Ths can be done two ways

1. Copy the entire document-to-html.xsl file to and change the appropriate value in the insertImage template
2. Create a new document-to-html.xsl file with only an import of the default document-to-html.xsl and the overridden insertImage template

Procedure

copy the entire document-to-html.xsl

1. Check if <wikidata dir>/resources/skins/yourskin/xslt  exists   (where yourskin is the name of the skin you are using ).  If it does not exist, create it
2. copy <wikidata dir>/resources/skins/default/xslt/document-to-html.xsl  to your skin  <wikidata dir>/resources/skins/yourskin/xslt/document-to-html.xsl
3. Edit document-to-html.xsl.
4. Find the section <xsl:template name="insertImage">
5. Change the image width value on the line
   

   <xsl:when test="$imageWidth > 801 and $linkInfo/p:linkPartInfo[@name='ImagePreview']">

6. restart the daisy wiki

Create a new document-to-html.xsl

1. Check if <wikidata dir>/resources/skins/yourskin/xslt  exists   (where yourskin is the name of the skin you are using ).  If it does not exist, create it
2. edit document-to-html.xsl.  Put in the following for the header:
   

   <xsl:stylesheet version="1.0"
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   xmlns:d="http://outerx.org/daisy/1.0">

3. Next, import the default document-to-html.xsl
   

   <xsl:import href="wikidata:/(webapp)xslt/document-to-html.xsl"/>

4. Then copy the insertImage section from <wikidata dir>/resources/skins/default/xslt/document-to-html.xsl and insert
   

   <xsl:template name="insertImage">
   ...
   ...
   </xsl:template>

5. Change the line to have the appropriate width for full-size images.
   

   <xsl:when test="$imageWidth > 801 and $linkInfo/p:linkPartInfo[@name='ImagePreview']">

Notes

The preview behavior can also be modified in the  <daisydata>/conf/myconfig.xml in the ImagePreSaveHook section  ( the above method is the more appropriate).  

In the section on  <previewMaxSize>250</previewMaxSize>.  When an image is loaded, if it is under this width (and under this height???) the real image will be used for the preview instead of generating a preview.   Likewise for thumbnails  modify the value <thumbnailMaxSize>125</thumbnailMaxSize>
