How to increase the size of the images within the image picker

Hi
Thanks for getting back to me.
I have changed the form to the classic layout as you recommended. Can you
please advise how I can increase the size of the images within the image
picker, the associated padding/,margin around it and how to increase the
number of images per row.

Many thanks

You need to add custom CSS code to your form to increase the number of images per row. Please inject this custom CSS code:

iframe#customFieldFrame_19 {

width: 1000px !important;

}

Here's how to add it to your form: https://www.jotform.com/help/117-How-to-Inject-Custom-CSS-Codes

I hope this helps. Thank you.
