That isn't a large site so it would probably be in your best interest to start over with a fresh install. I would also consider moving the site to another server where you have access needed to manage the filesystem and database.
Here is the current version of evolution:

Hi:
Ok I am going to continue to assume you are a newbie. If your overall goal changes, pls tell us so we can help you, I think its clear you will get support here if you ask a clear question.
This forum has a lot of developer users who have a lot of control over their sites and so we get the random comments about upgrading or starting over with the latest version. Easy for some but not for everyone haha!
If you really want to change this site significantly, you are probably better starting over. It makes little sense to try and understand this old site if you want to change it very much, you would want to use a newer version and its not always easy to move a site from an old version to a new version, things get broken and it can be a real pain. So, you would probably want to start fresh, using the same or new content with a new install and a new template (the template is basically the background green and the parts of the pages that are constant and unchanging on many or most pages, in this site the header and the links on the left are part of the main or only template.)
But if you just want to change the pictures as you asked, let's keep going with this goal.
Pls click on "manage files" under the resource tab, like in the picture. That is probably where you should be looking, there should be a folder under that called "images". "manage resources" probably isn't the right one, but click that too just to see what's in there. ;-) Indeed if you could give me pics of what you see when you click on both of those links, it would be great and we could finally find those images.
I thought the file tree on the left side would change like it does in newer versions. The file tree you see there is the pages of the site, there are still a lot of files that you haven't found yet. We don't need to go through all of them but you first have templates (which are html), then css and javascript, and so on. You haven't even found those yet, and they must be in there.
Gallery is another page of the site, its got the pics of the guy's family and friends and dog and so on, its not the place where the pictures that make up the site (kids_swimming.jpg) are at. Also the box is telling you just wrong info, it saying what is in website.com/, not the "gallery" folder. It seems almost to be like nothing is selected so it says path invalid.
Again, if you are thinking about a different goal, then let us know. But those images are in there and if that's all you want, then you can do it I think. However one small warning, when you replace the images you will have to consider the size of the new photos, in pixels, or the style may be affected.
