Problem with frontend k2 category layout

Did it, now the positions are much better, the "gaps" between k2 items are gone and are now the same size. But some articles are still just showing titles. Could the problem be in images sizes?

does that images show up at all when you for example enable some other template like beez5?

Yes, it does the same.

If it looks same then you edited article wrong

Hm, but i did the same with all articles. Intro image, text, read more and published.
I will try to replace the images.

I tried it, cant find the problem, since all articles are made in the same way
