I did figure this out eventually and am going to record it here so later, when i ultimately forget the twists and turns I took to make this happen, I'll be able to come back and see....For me it was not as simple as John (above) offered...First: Export photos from iPhoto into folder on desktop. Click on the folder and select from the top left corner File - Check info- click the box beside shared folder- scroll down to Sharing & Permission and make sure the other user acccount is added to who can read & write.
If you haven't done this already go into System Preferences- Sharing- check the box beside File Sharing- click on File Sharing as well and 2 windows will appear- Shared Folders and Users. Select the shared folder you want to use and in the User window add the other user account to who can read & write.
Next: Open Finder- select Public Folder- drag photo folder into it.
Now log off and open your other User profile. Open Finder. Select Macintosh HD in the side bar- select Users Folder- select the original User profile you want your photos from- select Public Folder- your photo folder should be there, drag it onto your Desktop or directly into iPhoto. If a block occurs saying you aren't alllowed to see this folder then you missed a step in the whole file sharing business.
Viola! it worked. Hope this helps someone else 😁
