Although you cannot upload images directly into DJ Event Planner, you can link an image to your account such as for your company logo, images of equipment, etc. 

First, you will need to have those images stored either in your own website (this can be in the backend on a hidden page) or in an image hosting site such as Google Photos, Imgur, Dropbox, etc.  This allows you to get a URL link directly for that image.  Make sure it is not the link to the page the image is stored on, but to the image itself.  For example, if you have the image stored in the backend of your website, open the image there, then right click over the image and choose “Copy Image Location” or “Copy Image Link” depending on what browser you are using.

Once you have that direct URL link to the image, then you can use that link within your DJEP account where your image is needed.
