Problem with frontend k2 category layout

I got it, you were right, the problem was in images editing (since after i inserted them in articles, i was resizing them. Now i would only like to ask one more question. How can i get all the excerpts, listed in categories on frontend,to have the same lenght? Can i somehow adjust the max size?

In language folder for each language you have one .php file where you have function:getSearchDisplayedCharactersNumber , check that out

It doesnt go, i get an "error on line" message if i edit that php file.
And i have to say sorry, i didnt solved the previous problem by images file, so that anyone reading this wont maybe get similar problems. Under"Layout options for multiple category selection" i had to set "links count" to zero, then all articles were showing normaly and none as "title-link" anymore.

Is there any other option to limit the lenght of items in category k2 blog menu?

You should only change number value, but you say that is for k2 so anyway that would not help
