When adding an image to my post and selecting the option 1:1, the image will not get the paragraph alignment (right) but will always align to left.
All other options will not keep the image 1:1:
2. Small - will centre image in the middle and will reduce it's size
3. Align to right/left will reduce image size and wrap text
4. Full width - will change image 1:1 size.
I do believe that if I select Hebrew as my main language, all setting should prefer a right to left paragraph and right alignment.
