[TYPO3-english] tt_news: image in latest, list and single view

[Rupali]

Hello List,

we want to show image in tt_news list and single view with different width
and height. Images are inserted in RTE using insert/modify image
button.Following I tried in constant field, but it doesn't has any effect.
images in list and single mode are in original size.

plugin.tt_news.displayList.image {
 file.maxW = 40
 file.maxH = 40
 imageLinkWrap = 1
 #stdWrap.spaceAfter = 5
}
plugin.tt_news.listMaxW = 40
plugin.tt_news.listMaxH = 40

plugin.tt_news.singleMaxW = 100
plugin.tt_news.singleMaxH = 100

plus in latest view no image and text are shown rather HTML code of image,
after heading:
<img src="fileadmin/templates/image_gallery/images/image-1.jpg"
style="float: left;" width="450" hei...

how to block image in latest view ? and list and single view with required
width and height?

Regards,
Rupali
