Lines under thumbnails??

I’m not sure of what I done, but all of my thumbnails have lines under them. This shows on my homepage and the product results page.

Any suggestions on what I can do to fix this?

Do you have a screenshot for us

Yes, I’ve attached it below.

I’m still searching the forum, but haven’t found any thing yet!!

Not too sure what it is, have you tried changing image type and also checked it in other browsers.
