Many of the WordPress website users fetches the in featured image section or content editor to be displayed at front-end. Now, the headache is if we want to change image to some new image then we will have to change it in all the posts types where this image has been used.. Upload and new image which will replace the in this media item.. Now, you will have to same images with different names exising png and new png to overcome this issue check the box to delete the new png at the time of uploading it... What about the the other sizes of the image, are they getting replaced.. Yes, if image existing png have 2 sizes or more as existing-150X150.png and existing-300X300.png then these images will also be replaced with the image and names of the images will be kept same... No, overall logic is we are replacing image with image, we take the name of image -> moves the original images to del folder -> take the name of new image -> create copy of new image and name it as original image... Depending on the aspect ratio of image we uplad the different thumbnail versions are created. If image is having large size but new image have only thumbnail., medium., medium large then large size for the image will be created by plugin and it will use the fulll size of the image...
