My theme is Fresh and Clean, which I think is fabulous.
The full image size in the post is 580px. That's okay.
Sharpness is not the best for all images.
I upload 800px images which generally are around the 100-130Kb size, sometimes just a fraction smaller.
I've noticed that my small 320px cellphone images look very sharp, whereas these 580px, WordPress-automatically-resized from my 800px images, usually look a little like pudding, meaning 'soft' rather than out of focus, even 'tho the original was very sharp. Here's an image as an example: http://jmnpixels.com/2012/04/12/jigsaw/.
Is there a trick I can use to make sure these 580px photos look as sharp as they actually are? Thanks.
The blog I need help with is jmnpixels.com.
