Where to change the pre-set twitter text/link for retweeting images?

(i had prior posted this in a wrong section)

Hi,
Anybody familiar with switching the long link offered standard in the basic tweet (by a shopperpress customer front end image), to the standard wp offered short url? ( I prefer to use the short url given by wp, than the long url, in this case I can use more text in twitter message)

If I for example want to tweet the image on this page – https://furnitureonlinesales.com/blog/product/4-piece-classic-white-childrens-bedroom-set/

I receive this text: Classic White Childrens Bedroom Set | Online Furniture Sales https://furnitureonlinesales.com/blog/product/4-piece-classic-white-childrens-bedroom-set/

However, in my wp admin, the posting also gives me the short link url: https://furnitureonlinesales.com/?p=182

How and where do I change this standard “long” link to the Short link in wp?

Thnx a lot,

Marty
