Unable to scroll images in mobile devices

Hi guys,

I’ve seen this issue long time ago but was not worried about it as I was not using images on my blog. Nou I re-designed the look of my blog and inserted in multiple sections and pages direct uploaded images. It seems that on any touchscreen mobile device we are unable to scroll the pages up and down by swiping on the images. I need to scroll on text or iamge free section to work.
Now this is really frustrating as 75% of my visitors are from mobile devices and this could be a business breakdown for me.
What seems to be the issue and how ca you solve it?

thanks
