How can I make the width of an image match the width of a message box? ✔️

Hi, I'm working on a product sales bot. In the welcome block, I display an image of the product followed by a text box describing the product and them some buttons.

The image is narrower than the text box. How can I set these up to be the same width across multiple devices?

Thanks

Copying and pasting between bots ✔️

Hi, is it possible to copy a set of blocks from one bot and then paste into another? I've tried several permutations but to no avail. I don't want to use bricks to do this.
Thanks 👍
