Here is the details I setting now:

the Images is a special field which I want to show image

field id: Images
Title: Images
Field Type: Rich text
Field moud: computed for display

formula:

db = context.getParentDatabase()
item_doc_id = context.getItem('ItemNo')
if not item_doc_id:
    return 0
item_doc = db.getDocument(item_doc_id)
images = asList(item_doc.getItem('image', []))
html ="" 
for image in images: 
  path_to_image = "http://www.kyholdings.com/image/plomino/"+image+".jpg" 
  html += """<a href="%(full)s"><img width="400" src="%(path)s" /></a>""" % {'path': path_to_image+"/image_preview", 'full': path_to_image+"/image_view_fullscreen"}
return html

Item list which I want to show the images(not text)

field id: Item_List
Title: Item List
Field Type: Rich text
Field moud: computed for display

formula:

db = context.getParentDatabase()
html="""<table border="0" width="100%">
    <colgroup>
        <col width="15%" />
        <col width="15%" />
        <col width="40%" />
        <col width="15%" />
        <col width="15%" />
    </colgroup>
    <tbody>
        """
item_list = context.getItem('Item_List', [])
for row in item_list:
    item_doc = db.getDocument(row[0])
    if not item_doc:
        html += "<tr><td>ERROR</td></tr>"
        continue
    html += """<tr><td><span style="font-family: verdana; font-size: 3px; ">%s</span></td><td><span style="font-family: verdana; font-size: 3px; ">%s</span></td><td><span style="font-family: verdana; font-size: 3px; ">%s</span></td><td><span style="font-family: verdana; font-size: 3px; ">%s</span></td><td style="text-align: center; "><span style="font-family: verdana; font-size: 3px; ">%s</span></td></tr>""" % (item_doc.getItem('ItemNo'), item_doc.getItem('NameEN')+item_doc.getItem('Packing')+str(item_doc.getItem('OPQTY'))+item_doc.getItem('QTYunitEN')+"/"+str(item_doc.getItem('Length'))+"x"+str(item_doc.getItem('Width'))+"x"+str(item_doc.getItem('High'))+"cm/"+str(item_doc.getItem('NW'))+"kgs/"+str(item_doc.getItem('GW'))+"kgs", item_doc.getItem('Images'), str(row[3]),  str(row[4]))
html += "</table>"
return html

It could work but could not show image.
