So it is important to keep frontend dimensions **smaller** than generated dimensions. * After making these changes you need to **Recreate thumbnails**. This is done to have a nice resolution for thumbs. * Then edit your gallery page and make sure **Image thumbnail dimensions** is set to the desired size here as well. * Thank you! * [karamarsee](https://wordpress.org/support/users/karamarsee/) * (@karamarsee) * [8 years, 1 month ago](https://wordpress.org/support/topic/thumbnails-quality-issues/#post-9962563) * I am having the same problem with poor thumbnail quality. I made sure the frontend dimensions are smaller than the generated dimensions. * Strangely, the images that are more “square” in shape have better quality than the ones that are “rectangular” in shape? Also, it looks like the images that are less than 800KB look better as a thumbnail than the ones that are larger – except – It’s not really consistent, because the line drawings are under 200KB and they are lossy as thumbnails also… * Please let me know what I can do to resolve this issue.

Unfortunately, it doesn’t seem to have done anything. I tried several times, choosing “apply” (next to “bulk actions”) and “publish” from bulk actions after selecting all images and clicking “recreate thumbnails.” Nothing has changed. 🙁 Any other suggestions? Am I missing something? * Plugin Contributor [Photo Gallery Support](https://wordpress.org/support/users/photogallerysupport/) * (@photogallerysupport) * [8 years, 1 month ago](https://wordpress.org/support/topic/thumbnails-quality-issues/#post-9973556) * Hi, * We are kindly asking you to contact us using this **[support@web-dorado.com](https://wordpress.org/support/topic/thumbnails-quality-issues/support@web-dorado.com?output_format=md)** email address. * Also, please mention the URL address of this post in WordPresso.org in your ticket. * Thanks in advance, have a nice day! * [karamarsee](https://wordpress.org/support/users/karamarsee/) * (@karamarsee) * [8 years, 1 month ago](https://wordpress.org/support/topic/thumbnails-quality-issues/#post-9990508) * When I contacted this email, they want my log-in info.

Thumbnails 1,2,8,9,14 and 18 look GREAT. But the rest are still really blurry/poor quality and even look worse than before? When I right-click on a thumbnail, and “view image” the ones that are clear are bigger. Not sure why it has recreated some and not others? The large images are fine. * Any other ideas, please?
