Images for Projected Digital Image competitions must be no larger than 1024 pixels wide by 768 pixels high.

Here's how to re-size your image (use a copy because this is going to permanently change it);

Choose Select Image/Resize/Image Size (Photoshop Elements) or Image/Image Size (Photoshop). Click on Re-sample Image/Bicubic then in the Pixel Dimensions area type in 1024 pixels as the Width. The Height will be automatically filled-in. If it is still more than 768 pixels then type 768 as the Height. Note that a square picture would be 768 by 768 pixels.

Click OK and save the file.

NB We receive many images that are 1024 pixels high - This is Wrong! Please double check that they are a maximum of 768 high
