Image sizes for each content type
The content types in T4 are set up to use specific dimensions, so it is very important to use the correct image size to ensure your images display correctly. For example, the aspect ratio of a banner bottom block image is very different to a 2-column colour block, so using the wrong size may squash or stretch the image, which will not give visitors to your page a good first impression.
In total there are five standard image sizes for use across the different content types. The table below lists these and the corresponding category (folder) in the Media Library, which is the storage area in T4 for documents and images. There is also a category for non-standard image sizes. These should only be used in the General content, Accordion items and Tabs content types.
The name of the categories indicates the image size that should be added to them. For example, the Banner bottom block 3000x850 is only for images that are 3000 pixels wide and 850 pixels high.
Depending on the content type into which you are adding an image, you must select an image of the correct dimensions to suit that content type.
