My property images are too big? Resizing Images
IDX Broker limits images to 1MB in size. You will need to resize or optimize your images so they are under 1MB in size. This is also important for website performance and speed as well.
There are several apps out there that can help you reduce the file size of your images. If you use a mac we highly suggest using Pixelmator, which has a feature called "Export for Web" which will reduce the file sizes.
Another tool available on Mac and PC is PhotoBulk. This tool will not only optimize but has other quick features available such as watermarking photos.
