Thumbnails are made when you upload images. If you change your thumbnail sizes, use this plugin to make new thumbnails. You should only need to use my plugin very rarely.
I have downloaded regenerate thumbnails
resized the thumbnails in the settings>media
went in and manually regenerated the thumbnails for the images
but nothing is happening. i have been scouring the forums. here is link to one of my images that is not filling up the margins to the left
here is link to one of the the images fit properly w/ no space to the left margin
I have no clue how to code. I am trying to do all this thru visual editor and researching forums and trying stuff out. I apologize if this is duplicitous. Thank you for any help
