I have read the TOS but am still struggling about attaching images. Most of the time, they come out just too small so without clicking them to enlarge, they are unreadable.
The below is an example. It is the same, unmodified image file, 237KB - 1600x832 pixels. For comparison, it is shown once if embedded from an image gallery in 'My Media', once when simply attached directly in the post ('attach files') and once by embedding as external link from Imgur.
I thought it is generally advised to upload to My Media and then attach from there. But if I do that I always end up with a Thumbnail size. When I check the gallery in which I uploaded the file, under the file it has 'Options'/'View all sizes' and there I have 'Thumbnail', 'Small', 'Medium' and 'Large' - with the 'Large' one having the original resolution. However, I do not know how to embed the image as large. In a new post if I go to 'MyMedia' --> 'Gallery Images' I can only select the image but without any option to pick any of these sizes. What am I missing?
Same for the directly attached image - this is not showing in its original resolution apparently - so how would I need to modify the attachment expression so that it does not automatically resize the image?
If I cannot find any other way, I will probably use external spaces like Imgur in the future, but I would very much like to avoid that if possible.
