Testing different image sizes.
The 400×600 gets cropped to 400×550.
The 600×400 shows the full thing. There are also specifications for 330×220 or 300×200.
The 1000×200 shows the full thing. There are also specifications for 330×60 or 768×154.
A 110×150 image (watches) is displayed as 625×550, so top and bottom are cropped.
A 1750×1313 image (gorilla) is displayed as 1170×550, again top and bottom cropped.
A 2064×2100 image (lil+goat) is displayed at 1170×550. Cropped.
But when I resize the image (within WordPress) to have a height of 550 (541×550), it still shows as 1170×550.
Trying resizing the image in Photoshop to 541×550 with 75dpi. Now it does show the whole image. And even that size with 600dpi.
There seems to be a max height of 550.
A square 550×550 is fully displayed.
