After talking to some of my fellow Bloggers, I decided to write down some instructions on how to do this:
<tr><td><img height="160" src="IMAGE 4 LOCATION"></td><td><img height="160" src="IMAGE 5 LOCATION"></td><td><img height="160" src="IMAGE 6 LOCATION"></td></tr></table>
Where do you get this info? Go to the actual item you want to show (in the seller's Folksy shop) and right-click on the main picture. Select 'Copy Image Location' and then paste this (by right-clicking) instead of the red text IMAGE 1 LOCATION (the black commas before the IMAGE 1 LOCATION need to stay there). You will need to do this 5 more times for each picture (you have 6 picture in total).
As an example, this is what the HTML code would look like to display 6 images from my Folksy shop:
You can now continue to write your blog below the images as normal. Don't forget to preview your final blog before publishing.
I hope this makes sense (and it actually works), if you get stuck, please get in touch.
PS: if anyone knows of a simpler way of doing this, please let me know! I'm still learning too.
