Uploading images to display in your Event Description is easy to do.
Simply click the "Add Media" button above the Event Description text box.
After clicking the "Add Media" button, a pop-up box will open prompting you to upload a file. Click Select File and choose the image from your computer. Once you have selected the image, click "Insert into page". You can also choose the "Media Library" tab to re-use any images from previous uploads.
Your image will then appear in the Event Description section. Click on the image to adjust the alignment and to edit the photo.
