Editing the Navigation Buttons and text pictures

I recently downloaded the Party Time template and put it onto my website (WITHOUT an FTP client).
Now what I need to do is edit the navigation buttons, as they say Home, Clubs, Parties, Bar and VIP.

Home is fine, but I would like the other four buttons edited:
1: Home (stays the same)
2: Games
3: Videos
4: More
5: About

Also, the text pictures such as this:


I would like changed.

Free Drink Party On changed to: Welcome
Our Party News changed to: Recent Updates
Night Party changed to: ZoomShare Forums
Our DJ's changed to: How it Started
Next Party changed to: Other Websites

Last but not least, could you change this picture:

All I want is the text changed to Welcome to CKeegan and the Details bit removed. I don't mind the beer.

Can anyone do that for me?
Thank you.

Here is a link where you can find a free image editors

and here or FTP programs

Must be one of those java programs which loads threw HTML... OUCH.

Thanks for the links, but sadly these are not what I need.
I need a photoshop user to edit them for me.

Will see what I can do for you in altering the graphics.
Does it have to be in that exact font?

Gone ahead without waiting for your reply re: fonts.
Now it's up to you to rename the files/file types to match those originals within your image folder.

Cheers mate, you've been a great help.
