[TYPO3-english] How to make images larger with pmkslimbox

[Olga Zhuravleva]

How to make images larger by click (in frontend) in content?
I have pmkslimbox.

In TS template write:
plugin.pmkslimbox.imgtext.maxW = 800
plugin.pmkslimbox.imgtext.maxH = 600

Include static (from extensions):
Slimbox(pmkslimbox)

as in manual.
But images not become larger when I click to them in frontend.
In tt_news it works but not in page content.
