Hi,
It seems that in your demo Home Decor 02, images that are displayed on hover have smaller width than the original image.
Please see attachments 1 and 2. In the attachment 1, you can see that the original image has dimensions 460x600px. In the attachment 2, you can see that the second image that is displayed on hover effect has dimensions 400x522px. You cannot see that in your demo because both images have exactly the same background. But this is perfectly visible if the background is even a bit different. Then there it is clearly visible that a smaller image is shown on top of the larger image, which simply looks ugly and unproffesional – please see screenshot 3 where you can clearly see the border around the image. You can easily reproduce it on your demo – simply use images with different backgrounds.
Can you please fix it?
