Resize a picture before you insert it into a Powerpoint show

Following are three options for resizing pictures before they are inserted in powerpoint:

Situation A: No special software needed on your computer except and internet connection. Solution: Use a web 2.0 application such as picnik.com

1. Log onto the internet and open picnik.com.

2. Click the Get Started Now button (you dont need to register!)

3. Click the Upload a Photo button and locate your original picture file (Note: it must be a flattened Jpg    file)

4. Click the Edit Tab > Resize button and enter the new dimensions: make the largest dimension 600pixels (ie either width or height - picnik keeps the proportion of the other dimension provided you have the Keep proportions checkbox ticked). Click OK

Situation B: Download free software on your personal computer/laptop for resizing images (school PCs have Picasa already)

Solution: Use Google Picasa 3. Picasa is a fantastic free image browser and editing program that is easy to follow. You can upload your images online to Google web Albums (like Flickr). Or you can export them to a folder or to email.

1. Click the Download button and follow the prompts to install on your computer

2. Locate the image you wish to resize using the browser pane to the left of the Picasa 3 window to locate the folder and then click on the image/s you wish to resize

3. Click the Export to Folder Button underneath the main window and create or locate a new folder to store your resized images in. Check resize > use the slider to the required pixel dimension eg 600 pixels > choose maximum image quality. Click OK. Your resized images can now be found inside the folder you designated as your Export Folder, ready to insert into Powerpoint.

Situation C: You have access to Photoshop (available on all school PCs)

Solution: Use Photoshop

1. Open Photoshop and go to File > Open and select the image you wish to resize

2. Go to Image menu > Image size and change the largest pixel dimension to 600 pixels. Click Ok

3. Check any layers are flattened and Save As a maximum quality jpg file. Remember not to save over the original.
