Can cropping be avoided in thumbnails, if original images have different height ?
I saw your fix for another theme (enter 9999 as height value) and tried in Velvet without luck.
I did regenerate thumbnail - and changes are working fine with any 'real' height such as below - but with 9999 the image just disappears.
It is for this code:
$avia_config['imgSize']['portfolio'] = array('width'=>210, 'height'=>210);// small preview pic for default portfolio (4 columns )
Create a new thread and tell me what problems you are encountering and what you want to know. 
There is no step 3 :)
