EE 2.0.1 resizing image problem

I am desperate. I need only simple thing: upload image (this use as big image) and with some extension or plugin automatically resize it and use as thumb.

I am tring core 1.6.8 in local and for resizing i was using FIle extension (http://docs.markhuot.com/ee/extensions/file).

Now I buy EE 2.0.1 and there isnt working.

I found ImageSizer but this isnt working too.

My code:

{exp:imgsizer:size src="{obrazok_puzzle}” auto=”135”}View{/exp:imgsizer:size}

But its like its ignoring, nothing show. Yes i change atributes to 777, read posts in forum but i cant do it..

Please can somebody help.
