Most sites use a default social image when posting information to facebook, twitter or google.
If you would like to customize this image follow these instructions:
- Go to SETTINGS - System Files -> IMAGES tab and replace the file 'socialimage.jpg'
- filename must be the same
- has to be .jpg file
- best results are the exact size 600px width x 315px height (remember Twitter crops left/right off to make it square).
Need to test your new Facebook image??
After updating your facebook image you must manually "scrap" the URL using the following link. This may take a few hours while the cached images are still being used so best expect a slight delay at this stage.
