WordPress Image Use Guidelines

Our website is the public face of MLML. We want it to be rich in multimedia and visually appealing. The images we use on our website must be used legally, according to their copyright and licensing. The guidelines below will help to make sure that the image specs are appropriate for use on the web and that we have the right to use a photo. Pay special attention to statements of allowable re-use and how the image owner would like you to give them credit. Please also see our Permitting Guidelines.


Image Specifications


    • Slider
      • Upload original image, then (within WordPress) resize/crop to:
        • Width - 1400px
        • Height - Anything you want, but keep it consistent amongst all of your slider images or it will look bad. For reference, the main website uses 500px for its slider images.
    • Everything Else
      • Original size, high resolution images. WordPress will automatically generate appropriately sized thumbnails.
      • Enable Lightbox whenever it is appropriate (usually all the time).

File Types:

    • JPG - For photos.
    • PNG - For drawings, graphs, logos, etc.
