doesn't work

Nothing is showing up 🙁

I set the thumbnail size to “150” for both dimensions.
I made sure there were no spaces in the tag, just in case.

May I suggest using shortcodes to place the gallery where we like? I want mine to appear in a page with text. Where will it go in relation to the text?
