The pictures i just dumped into iPhoto are HUGE!

Question

Hi!  I just shot pictures of a very important soccer championship.  I came home, plugged camera in, opened iPhoto (which used to open automatically) and imported all pictures from camera.  I chose 'delete originals from camera.'
Then I went to Picasa and uploaded them there to share with my boss who would then be able to put them on his website for the team.  I noticed some were rejected and the entire storage bank for pics was full.
When I investigated a little further, I realized that all of the pics are over 4MB ea!
I don't know why they're so huge and have no idea how to change them. 
Can anyone help??
Thanks,
Christine

When it comes to Picasa or iPhoto the simple advice is to pick on horse and ride it. You're using two apps to do the same job and things are fallign through the cracks:
With the last pics I took for him, I must have uploaded directly to Picasa because I'm not finding those in my iPhoto library.
You can upload to Picasa Web Albums from iPhoto, - google for the iPhoto Picasa plug-in - or just use the standard uploader - the first of these here:
There are many, many ways to access your files in iPhoto:   You can use any Open / Attach / Browse dialogue. On the left there's a Media heading, your pics can be accessed there. Command-Click for selecting multiple pics.
(Note the above illustration is not a Finder Window. It's the dialogue you get when you go File -> Open)
You can access the Library from the New Message Window in Mail:
There's a similar option in Outlook and many, many other apps.  If you use Apple's Mail, Entourage, AOL or Eudora you can email from within iPhoto.
If you use a Cocoa-based Browser such as Safari, you can drag the pics from the iPhoto Window to the Attach window in the browser.
If you want to access the files with iPhoto not running:
For users of 10.6 and later:  You can download a free Services component from MacOSXAutomation  which will give you access to the iPhoto Library from your Services Menu.
Using the Services Preference Pane you can even create a keyboard shortcut for it.
For Users of 10.4 and 10.5 Create a Media Browser using Automator (takes about 10 seconds) or use this free utility Karelia iMedia Browser
Other options include:
Drag and Drop: Drag a photo from the iPhoto Window to the desktop, there iPhoto will make a full-sized copy of the pic.
File -> Export: Select the files in the iPhoto Window and go File -> Export. The dialogue will give you various options, including altering the format, naming the files and changing the size. Again, producing a copy.
Show File:  a. On iPhoto 09 and earlier:  Right- (or Control-) Click on a pic and in the resulting dialogue choose 'Show File'. A Finder window will pop open with the file already selected.    3.b.
b: On iPhoto 11 and later: Select one of the affected photos in the iPhoto Window and go File -> Reveal in Finder -> Original. A Finder window will pop open with the file already selected.
AS for the size of the images, that's entirely a setting on your camera.
