Sorry for top posting but it seems we can't get expanded versions of the graphs by clicking. Would this be possible ?

I fixed the first two graphs using a link type of reference. Is this the way you want them? If not, let me know what code I need to use to fix them.

I will fix the others as well, if this method is OK.

Almost right. I think the problem is your have .jpeg instead of .jpg for the file ending and its going to download for me.
I checked some other posts with png's and they open in a new tab on firefox. Also a small thing if your doing graphs I like png's since they scale much better than a lossy codec like jpeg. I think you will see much clearer small versions with png vs jpeg.

Great work and I'm not one to nitpick but I think this will be a important post for future reference.

I am afraid I will need instuction to do png's. I have figured out one way of doing things that sort of works - that all.

Most programs that save have a option to save as png. I'm not sure what software your using.
You can email me my address is in my profile I'm sure I can find the answers to your questions. Google may or may not work questions like this tend to return lots of junk.
