iPhoto allowed you to email photos from within the app, letting you choose a nice layout (like a birthday card, etc). I can not find any email capability from within Photos; any tips on emailing from within Photos is appreciated.
Not directly, as far as I'm aware, but you could make a greetings card, then save as PDF…
- Select photos to add - 13 pics appears to be the limit for the automatic layouts.
- File menu > Create card
- Choose flat style
- Select a theme, then Landscape or portrait
- Once selected, 'Options' under the card lets you choose number of photos & layout
- The Options 'inspector' is context-sensitive, so depends on what you select as to which editing options you see - number of photos - colour, crop & zoom etc.
When finished, right click anywhere in the card & 'Save Card as PDF'
Attach to email.
This has the advantage that it doesn't need the HTML that would need to be embedded in the email to achieve this without PDF, so it becomes portable, outside email.
Photos will also save this layout permanently, for if you ever need it again, or until manually deleted.
