Product details image is not resized

[psm]

Dear all,
I would like to ask you if you do not know why picture is not resized when I open details of some product? It is in full size and there is also error message:
Notice: Array to string conversion in /templates/megawebshop/html/com_virtuemart/productdetails/default.php on line 144.

I just changed something in virtuemart settings and I cannot remember what. But I tried to remove categories from product detail page when it was changed.

I have virtuemart version 3.2.0, php 5.4.46 and joomla 3.6.5.

Thank you very much.

These problems are created by your Joomla template. You need to contact your template developer to fix the issues.

Yes, I changed code and made mistake, but I did more things in the same time, so I forgot it.
