Here are Three Points to Practice:
1. Height & Width of Images:
Whenever you insert an image in your article, make sure that its HTML (HyperText MarkUp Link) code contains the height and width parameters.
This plays a huge role in page loading speed. When the browsers detect the height and width tags, they will continue loading the text on the page as it defines the height and width parameters of the image. This enables the text and the image to be loaded simultaneously.
If you don’t mention the height and width in the tags then the browsers will load the text till the image and then stop the text and load the full image and then the remaining text. This will put a strain on the servers, especially if the server is HDD and has to start spinning for image fragments everywhere and it WILL increase the loading speed of the page. Solis State Delivery Servers are FAR best for images. See image below;
2. Remove Hyperlink from the Image
When you upload the images in your article, WordPress will automatically add a link in the source code to the image location (i.e. /wp-content/uploads folder).
Not only does the hyperlink serve to funnel the link juice to non-important image page, but it also distracts users from the main purpose the image is there. The main thing is to keep the main thing the main thing. If you do not remove the Hyper Link, when the visitors that are reading the article accidentally click on the image, they will be redirected to the image and may not or know how to return to your article where they had the credit card in their hot little hand to make a purchase and now your kids will have to eat beans and Ramen again because you did not listen to The Teddy Bear.
3. Lastly, Select "NONE."
Loes taught me this. When you upload the image, on the right side, under the “Attachment Display Settings”, you will see an option that says Link To. Click on the drop-down menu and select None to remove the hyperlink.
