On my Mac Mini I did the following:
Open Photos
Find the image to resize
Right click the image
Highlight and click "Edit with"
Click "Preview"
After image opens in Preview, on Menu bar, Click "Tools/Adjust Size"
Make sure it is adjusting in pixels and select 1200 or so. It will scale to the aspect ratio of the original photo
I usually select File/Rename and then File/Move to: and put it into a folder on my desktop named "Misc Photos"
Upload the scaled image to your gallery
Navigate in your gallery to the image to upload.
Click the image to make it larger.
Click the Share links icon
Copy the BBCode
Click the small image icon to the left of the “Font” selection
In the “Please Select” drop down list, click “Extract Blog Entry” and paste the BBCode in the textbox
Your image should show up in the posting.
Just did that for the image below.
If you find errors in these instructions, please let me know so I can correct them
