HELP... [...]
I have done it many times for single photos, but say I send four photos..
1. They always are vertically down the page and to me looking odd ...
2. Thankfully photos come out a reasonable sized automatically I assume....
So my question being, is there away to do HORIZONTAL photos because be damned if I can find it 
Plus does size really matter!! can I set the dimensions of my photo, if they need correcting.
I expect someone is going to show me something very obviously easy now 
Once you have published your post and your photos by default appear VERTICALLY, click MODIFY, which will bring up your post for editing.
The photos in your post will then show
[as hyperlink code within square brackets] arranged VERTICALLY.
Each set of
[hyperlink code within square brackets] can be shifted or cut and pasted to align the photos HORIZONTALLY.
How many photos can be aligned horizontally may depend on factors such as device used, screen size, photo size etc, or any other limits pre-set by the UKP software.
