Any updates on how to make images smaller?

Hi

I spoke to @Jack Kitterhing in live chat last week regarding the icons appearing in my recent custom posts widget on my site. Basically, I just want to make the images a bit smaller as they look big and messy at the moment.

I think you said you were going to email me about it Jack? Just wondered if I've missed the email or whether there's any news on what I can do about this?

Thanks

Sally
