 * Hello,
    unfortunatly I don’t understand image sizes in WordPress. I resize my
   featured images before uploading them to the Media library so they have _about_
   the size of the featured image in the actual post. For this I meassured the featured
   image manually with a screenshot. I don’t even know if this approach makes sense.
   Now I am afraid to ever change the featured image size because I would have to
   reupload all the images.
 * Now all my posts are displayed on the front page in a grid using a 3rd party 
   Plugin and I wonder what image size is used there to display the images? I am
   afraid that this would load the full size image for all the thumbnails.
 * Also I want to start putting images into the posts themselves and I have absolutely
   no idea what image size to choose, especially since it can be displayed on different
   screen sizes.
 * Another thing I dont understand: When I zoom into my browser, the image is much
   much clearer than when I zoom into the same image on my PC. It gets much more
   pixelated on my PC, even tho it’s the original file. Why is that possible?

 * Image size settings are suppose to be set in:
 * Settings => Media
 * But it might also depend on the theme you use.
 * Right click on the image in Google Chrome and I have found that it shows you 
   the image size used and what it was with the theme I use. So if it is reducing
   them all to the same size then I would try and resize them to that size in the
   first place if possible.
 * Some of your images in the 1st column are set at 300x150px and the 2nd column
   different sizes but very similar.

 * Thanks for the tip with Chrome! That’s very helpful. So the thumbnails seem to
   be correct. So when I want to put an image into my post, it’s just a matter of
   how big I want to display it, right?
 * I come from Android development and there image sizes and device memory are a
   pretty big deal, but I guess on PCs with good internet connections it doesn’t
   matter as much if the image is unnecessarily big?
