1) If you have a large number of high resolution images you've added, you may experience a longer wait time.
Why: If you've added images using a url, the system will need to retrieve each image and download it. This process time can vary depending on the image file size.
TIP: Try uploading images from your computer to cut down the download time. Follow these steps to save an image from the internet.
- Right click on the image.
- Select "Save Image As"
- Save the image to your computer.
- Upload the image
