Hello sir,
first of all , i would like to ask whether you site is active or not, if yes, may i have the link?
second, as you said that your site is responsive, then there must be media queries and their listeners changing the size of images according to screen, the function aq_resize($img,350); is passing the image and its size as an argument to implement the query according to screen size, i think the problem is in that particular section, i am sure that the problem can be solved easily, Hire me for your work, i'll do it perfectly and in time, looking forward to discuss more details with you, Thank you
