Stadium picture

Hi, not sure if this is in the right forum but I'm hoping someone can help. I have recently downloaded the stadium pack (which is great, top work to those who put it together!) but I'd like to add/change a few for my personal save. How do I do this? Do I need to download any particular programme or something? Any help would be much appreciated, thanks!

They're pretty simple to change actually as long as you have an image, all you need is photoshop, open up the image in there and get it down to 400x240 size, then fx (at the bottom of the layers bit), stroke, make the colour black, Position set as Inside, opacity 100, size 1px, then just overwrite it with the stadium that you're changing, (you can find the ID for that in the editor, or in game if you have the ID at top enabled) that's how I did my updated Salford at least

Guys, could I ask you where to download an updated version of stadium pack for FM 2018?
