Thanks for your quick reply! Doing what you said, I was able to solve one issue but created another. I changed the limits for the image size, then I ran the plugin to re-generate the thumbnails. That worked to change the size of the thumbnails – however, now my images are all blurry because something is instructing the thumbnails to shrink the images and then blow them up again. I have tried uploading images the exact size of the thumbnail, but it still shrinks them and re-enlarges them. Could you please make a suggestion of how to fix this? I would much appreciate the help. ??
