Hello Linda, do you mean add a photo to an existing blog you already have on GoY ?
If so, open up your blog > edit blog > include photo's >
publish.
Unless you meant something else of course!

Linda - I don't think you can. You need to 'add a plant' first, with a photo if you have one, then after that you can link any further photos to that plant.

Once you've posted a photo before adding the plant to your 'garden' section, you can't work backwards. You'd need to take another photo and then link it.

Been there, done that! LOL.

I have just redone it, so it has appeared twice on the Member's page. Thanks anyway.

Yes, that's exactly what I meant - it's the only way of doing it after you've posted a photo 'before' adding a plant - but as long as you're happy about that, it's fine. :-))
