This is the simplest and easiest way to add an image to a page:
Use this approach if you want to add attachments like PDFs.
STEP 1 UPLOAD YOUR FILES
Setup a dropbox account (free) and create a folder that you will store all your web files in.
We've called ours web. Add all your files to this folder.
STEP 2 CREATE A LINK
Click on one of the files you want to add to your artsphere website.
Click on the share button at the far right of the file.
Click "create link" and then click "copy link".
STEP 3 INSERT THE LINK
Go to your Artsphere CMS and on the page you want to update, click the insert link button in the toolbar.
Where it asks for a URL, paste the link from Dropbox.
STEP 4 TWEAK THE LINK (OPTIONAL)
If you want to show the attachment in your web browser not a dropbox window (see examples below) change the last bit of the link that says dl=0 to raw=1.
