under construction plugin removed but its picture remained

hi,
this is a very tricky problem i am having, i was using underconstruction plugin and had a picture coming soon written on it.. so now i deactivated the plugin and removed its files as well. the website loads corrected, but when i wana share its link, then the image that is to be shared on social networks is the underconstruction image i used before, not the actual picture that i have on my website page.. although i deleted the picture from the library and checked via ftp and it’s not there.. i don’t know what to do… i cleared the cache of my browser and even restarted my laptop..

This is my website, if you share to facebook you will know what iam saying.. https://seemaye-web.com/2013/12/05/5-different-types-of-logo/
