Resizing Images

Hi, I have created a page, added a bloc in the main area. I have added some images. I have resized the images so they all are the same size )in Photoshop), saved them down to the website. When I reopen teh website from its folder, all the images have reverted back to their original size.
I am using the trial version at the moment.

perhaps this will help from @Eldar :

We haven’t got much to go on. But it’s likely you have embed assets turned on. So the images have been saved in the project file itself. You can use the media manager to manage your images.
