Product Image not resized

Hello and thank you for the great Plugin.

I used the plugin, the catalog mode images fixed perfectly, although a lot of them seem pixelated but the product images still show too large.

I cheked the woocommerce single (600×600) i regenarated thumbnails but the issue remains.

I cleared all kind of cache.

What can i do to show all the images in the right size and fix the pixalated images?

Thanks in advance
