Freatured image is not responsive on mobile phone


first of all, I really love your theme! I really appreciate your work and I am very happy so far.
I have always used a normal picture for my posts ( and it worked just fine but after that I had <!–more–><!–noteaser–> and content. When I wanted to share the page on facebook or any social media, there was no bild shown or header/widget of the site instead. So I used the function freatured image, which works fine, but! When I look at the site on my mobile phone now, the pictures are not responsive…

Please help me, this is my site:

Looking forward to your answer, have a nice day!

Hi @tupamarek,

I hope you are well today and thank you for your question.

I have tested it using and found it’s working fine as shown in the attached screenshot.

Have you managed to make it work?

Please advise.

Kind Regards,

Sorry to pitch in here but I think I’m having the same issue, but with the Dazzling theme. For some reason some featured images (uploaded to slider width) are not responsive on mobile phones. I already posted about this issue in the Dazzling theme forum but I haven’t got a response so far so I thought I’d check the Sparkling forum to see if anyone has the same issue. Please check out screenshots of the issue on my original post here. Anyone have any suggestions?? I have been stalling the launch of my new site for two weeks since I can’t for the life of me figure this out… THANKS!!!
