First off, try to keep your images at a small to medium size. When you add an image to your post you can resize it with a click and drag or a click and select the size. If someone wants to see the image in a larger scale they can click on it.
Next, we need shorter posts. I love the stories, the tips, the tutorials, the self-promotion and more that everyone posts and I've never given thought to length. But I've had a few emails about the difficulty of viewing the blog when there are long posts - some people have slower connections, view on other devices (like iPods), or use a lower resolution. So, please continue to post your long posts, but insert a JUMP BREAK in it so it's shorter on our main page and those that wish to read further can click the jump link and do so.
Here's how. Write your long post and then select the point at which you want to insert the jump break. You do so by clicking the broken page icon in the post editor (you need the updated editor - see below).
This inserts a grey line into the post that will appear as a "read more" link on the main page. The rest of the post will be seen after the jump - on the post page.
Settings link in your dashboard - the settings tab, basic - and scroll down to Global Settings, Select post editor... select the "Updated editor" option.
I would appreciate if everyone followed this rule for the sake of readability for everyone. So, post those long posts!
