# Organization Logo
You may add one or more images to each organization. Adding an image to an organization makes that image available to be included in the auction catalog and forms.
Images are best having less that 1MB in size. Only PNG and JPG file formats are accepted.
To upload, or add, an image use one of these methods:
Under Actions, click Add Image; or,
Click the LOGOS tab and then click Upload New Image button.
The precise dimension is not critical (since screen sizes will vary) although a width roughly in the following ranges will work well in most cases:
- for "full-width" photos or images, a width of around 1200px is best;
- for "half-width" photos or images, a width around 600px should be used; and,
- page background images work well up to 1600px wide.
