Unfortunately Highend is a disgrace in this regard. I am unable to login to their support centre or forum. Keep receiving error messages. One of their experts built this slider for me for a cost but could not fix this responsive slider issue. Therefore came here to see if anyone could offer assistance.
Is Fixrunner reliable? They just emailed me advising that they can help and will only charge after fixing the issue.
Just to clarify, the slider images are too large in the mobile version. Would appreciate assistance.
