Image formatting

Can I use an image that I did not create?

To use images that you did not take or create you should get written permission from the copyright holder. Images taken by other photographers or that are found on the internet, in other books, newspapers and magazines are most likely to be copyright protected. You can visit the Maltese Copyright Act, Chapter 415 of the Laws of Malta here.

What colour mode should my images be in?

Both RGB and CMYK colours are modes for mixing colour in graphic design. Fundamentally, RGB is best for websites and digital publications, while CMYK is better for print materials.

What is image resolution?

Resolution describes the number of pixels within an image and image quality increases with resolution. Image resolution has everything to do with printing your image. When printing an image, you may encounter the term PPI or pixels per inch. This literally refers to the number of pixels that will fit inside each inch when printed. 
It has nothing to do with how your image appears on your computer screen, which is why images you download off the internet usually appear much larger and higher quality on your screen than they do when you print them.
Resolution can be expressed as the number of pixels per dimension (e.g. 1200 pixels wide by 750 pixels high) or as the number of pixels within a specified area (pixels per inch or PPI). An image that has a resolution of 300ppi and is 10 x 6 centimetres in size, will be 1181 pixels wide = and 709 pixels high. In general, the more pixels you have per unit area, the more detailed the image will be and the larger the file size.

How do I determine the resolution of an image?

In windows, you can right-click an image to view its properties. On the Details tab, under the Image heading, you should find the Width, Height and Horizontal and Vertical resolution.

What resolution should images be for print?

Ideally, images for print should have a minimum resolution of 300 PPI at the size you want them to appear. Any image having a resolution less than 220 dpi is considered low resolution and should not be used for print jobs.

How do I organise my images to submit them for typesetting and design?

For chapter books, the images are best organised in folders – a folder for each chapter. In each folder include the images in JPG, TIFF, PSD, EPS or AI format and a Word Document with their captions. Your images can be renamed with numbers and your captions should refer to the same image number. If you have any extra images which you want to submit in case we need to substitute or include additional images, create another folder called ‘extra images’ in the chapter folder.

Where can I get images?

For generic images or illustrations, we have a subscription with If you find any images which you want to use from this website, please provide the image id in your captions document.
