iPhoto Help

a simple search on google would answer these questions.

Photo editing software for Mac? Are you serious? Dude:

Photoshop Elements 6
Photoshop
Apeture
Picasa
GIMP
iPhoto itself....

 

To change the size, click Edit and then Crop.

For alteranative photo editing there is Gimp (free), Adobe Photoshop Elements (75$?) and for about the same price there is Pixelmator, which I prefer.
You can have iPhoto still manage your photos and use any program as an external editor, which is very nice.

 

Crop cuts off part of the image, unless that's what you're looking to do. If you have Mac OS X Leopard, you can use Preview to resize the image. Drag the image to the Desktop or set iPhoto to use an external editor when clicking Edit. Once the image is in Preview, under one of the menus is an option for Image Size. In there you can change the resolution of the image, which preserves the viewable area of the picture unlike cropping. Once done, save the edit on the Desktop. If you already had a copy on the Desktop, just overwrite it. If you set Preview as the external editor, you cannot save the image in the present location because nothing except iPhoto can write inside the library package. Then reimport the image back into iPhoto or do whatever else you want with the resized image.

 

It's okay Angel. Sadly, sometimes it's easy to forget that there are people new to the mac world who really aren't asking questions to be silly but because they need the answers.
When I do my photo editing, I use Photoshop Elements usually but like someone said, Gimp is a free alternative. I have also (when not sure what to do) downloaded trial versions of the various programs and used them until the trial period was over and if I didn't love them, poof! I deleted them.

 

You can resize images by exporting them in iPhoto, it'll go ahead and reduce the quality and/or the size (under custom). Good luck.
