Thank you. I'd rather you didn't remember it for other blogs, thanks!
Now this would be fine except I didn't want square tiles but oblong ones, just as it was before.
I have had the gallery widget working in this way, just as I had an ordinary text widget with a gallery working fine. It's just since I tried the mosaic and wanted to go back again to the ordinary.
I'd be grateful if you could have a look at fixing it please as I liked as it was before.
Would it perhaps be better if I went back to a gallery post in a text widget? Now if that is the best option, I have a question about that which is how do I stop that post also displaying as an ordinary post would?
If all else fails, would it be possible to create this in CSS? (In which case I shall have to get someone to fix it for me.)
