Loading Pictures on eStore 2.3 Theme by Elegant Themes

Hello all!

I need some help on how can I overcome the problems I’m having with some pictures I’m trying to load on my website, which are turning out uggly on Featured Slider of the theme I’m using; which is eStore 2.3. by Elegant themes.

The picture loads well, but when those posted on featured slider are flashing they become so bigger like they’ve been zoomed out that pictures look like bitmap.

I don’t know if I’ve been articulated the question properly, but give a look to the website in question, (allkitfm.com) and you’ll see the flashing images and how do they show up.

Thank you in advance for your help
