I have been reading all the posts relating to this, and it seems some have not been optimising their images before posting.
However, i have, and still have the same problem.
I save my images for web using PShop, ensure they are 72dpi, and that the width pixel dimension matches that of of my blog theme (584 pixels).
However, once they are uploaded and inserted into the post the blog images look soft on a PC, iMac, iPhone and other devices - all with the most recent browsers.
However, on some of the blogs, i left the hyperlink in, so that if you click on the picture it takes you directly to the JPEG that was uploaded - now this JPEG is sharp, as i uploaded it.
Why does WP make the images soft in my posts despite all my efforts before hand - as a photographer, image sharpness is an important factor that must be displayed in my images.
The blog I need help with is butterflyeffectphotography.wordpress.com.
