Create Your Gallery
To create you gallery you need to open Image Capture which can be found in your Applications folder. After opening Image Capture you will want to connect your camera, cell phone or memory card to your computer. The device will appear on the left of the Image Capture window under "Devices." If you are reading a memory card it will most likely appear as a white drive icon with an "Untitled" name. Cameras might appear the same way or they might appear as a camera with the brand name. iPhones and other iOS devices will appear with that device's icon and the name it has been assigned via iTunes. Click the device and the photos available will appear in the window to the right.
If you want to use all of the images off the device you can skip ahead to the next step. If you only want to use selected photos you can do that too. Hold the "Command" key down and click the photos you want to use in your gallery.
The next step is to tell Image Capture what to do with these photos. At the bottom of the window you will see "Import To" followed by a pull down menu. In that menu you have numerous options. One of these options is "Build a Webpage." This is the option we want.
You can then click "Import All" if you are using all your photos, or "Import Selected" if you are only importing select photos. If you are an iPhoto user this process should seem very familiar.
Image Capture will then use those photos and create a very simple and generic website and open it in Safari. You wil see thumbnails of images which when clicked show the full size. Nothing fancy here. You then need to save this website to your computer for future viewing and/or uploading to the internet.
The website will be located the Pictures folder of your user folder. In that folder (probably at the bottom) you will find a folder called "Webpage" with the date and time you created the site in the name. In that folder will be the files you need to upload to the internet. You can move the folder, rename it, or leave it in place.
All that is left now is uploading it to the internet, as mentioned above.
