How do i resize my new collection photos for my existing store

I created my store years ago but went inactive after opening my brick and mortar. I am about to activate my store again but I want to change a few things. I’m trying to change my collections photos but I’m having a very difficult time getting the sizing correct. I know I had issues before but eventually got it how I needed it but this round I’m stumped. I am open to any advice available on this subject. Thank you!

@Sillybillysllc , Hope you are doing well.

Could you please share your store URL? Also, the screenshot where you want to change and how you would like to display.

Hi @Sillybillysllc ,
Can you kindly share your store link (with the password, if any) with us? We will check it and suggest you a solution if possible.

is there any way to get someone to contact me about other questions i have but can not find answers too?
