Did you notice the issue? Some people straight add the precise 5MP picture! The WordPress theme will load your entire 5MP picture (that’s 5 x 10^6 pixels) and ask the browser to shrink it to the required dimension of 150x150px. In essence, the browser shows solely 0.0045% of the unique picture!

3. Use Progressive JPEGs
For the widespread man, JPEGs are of two varieties – Baseline and Progressive. Visually, each are identical. The distinction lies in the way in which they’re loaded:
- Baseline JPEG has just one layer – containing the entire picture. When requested, your entire picture is loaded at one go.
- Progressive JPEGs compose the picture with a number of layers. A Progressive JPEG picture is loaded layer by layer, which progressively will increase in high quality, in the end providing you with a lossless view.
All main picture resizers mean you can save pictures as Progressive JPEG.
4. Allow Lazy Load
Lazy-Loading is a wonderful useful resource saving method the place a picture is loaded solely when the customer scrolls all the way down to the view-frame of the picture. Contemplate an article – “15 of the Most Gasoline-Environment friendly Automobiles in 2014”. Naturally, this text will include not less than 15 pictures. And irrespective of the peak of the show machine – monitor, pill, or smartphone, you can’t match all 15 pictures within the view-frame.

A lot of individuals have a tendency to go away these fields clean. That is very detrimental for search engine optimization, and also you lose out on visitors.

If you add a picture, WordPress resizes it into a number of variations – Thumbnail, Medium, Full Dimension, and so forth. This may be modified by the developer. A nicely coded theme will serve the “Medium” sized model of the picture, thereby saving bandwidth.
The Picturefill.WP plugin will substitute picture tags with a brand new <image> component that may serve totally different pictures primarily based on media queries. It’s pretty experimental (meaning there are bugs) and shouldn’t be used on a stay web site.
9. Picture Captions
Captions aren’t at all times mandatory, though in some circumstances, it’s required – akin to screenshots in a tutorial. Captioning pictures helps readers perceive the subject higher, whereas boosting your search engine optimization.
