Bad quality thumbnail images

Please post an URL to the page with the problem so everyone can see.
The images I’ve seen in some of your pages aren’t loaded by Nextgen.

thanks

Your correct URL is https://www.gardensolutionscheshire.co.uk/gallery-and-testimonials/
Anyway, I see again images uploaded with WP media gallery, not Nextgen, so maybe you are in the wrong forum.

Sorry, I’d changed them back temporarily. It’s back as NextGen now.
Any advice would be greatly appreciated.
I was also wonder how I could control the size of the images in the light box?

Thanks.

OK, check the image dimensions and quality (for thumbs and image) option settings because I think there’s something wrong since some images are resized larger than the original when opened in lightbox, hence they are blurred.
It would be better resize images with a graphic software before upload them, ready with the desidered res and full dimension for the lighbox display, not larger than about 800/900px long side. In this case you have to leave empty “what should images be resized to” field (image options).
But if you want resize them once loaded follow this guide.
