Thumbnail size?

A while ago I saw something in an improvement list saying that Hika was working on increasing the size of the thumbnail on the item page vs. the sidebar and list modules.

Is this something that is still being worked on, or something that I can alter in some code somewhere?

Example

TheRollerskate.com
Notice on my home page, on the right, the thumbnails fit perfectly and are fine.

But if you go to one of my products:
Lift Bridge

As you can see, the thumbnail is the same size on the page itself. Just wondering if I can get that image way bigger on there.

Ok, I was able to successfully change the thumbnail for a category page with a bunch of products on it. That's pretty cool.

But I'm still not sure where to change the thumbnail size of the picture on the product page.

I looked at the Display tab under Configuration, but I didn't see anywhere to change a thumbnail size.

I have HikaShop Essential 1.5.4, is this the right verions?

Ok, I found what you were talking about in files. But it seems that if I edit the "thumbnail" size under Files, that not only does that adjust the thumbnail on the product page, but it also increases the size of the thumbnails on a category page and a sidebar module.

Is there anyway to edit these two thumbnails independently?

Ok, I got it for the most part. Thank you for your help.

However, I have some images showing underneath my category pages.

I'm sure this is just a setting somewhere, but I can't figure it out.

Ok, that helped. I appreciate it.

Somehow I figured it out...I'm pretty sure I didn't do it the "right" way, but the end result on the site is what I want, so...yay
