I am using PBWorks as a Wiki generator which has a limited graphics editor. What it can do however is import JPG files. So, using Photoshop (I have version CS3) I thought I could take a JPG photo, add hotspots to it and then save it as a JPG before uploading it to the Wiki system. Then I could insert this JPG file into the appropriate part of the Web page (PBWorks generates).
Is this possible to do? To date I have totally failed!
What are Hotspots supposed to be?
Wikipedia does not seem to mention them in the JPEG entry, so I doubt that they conform to the standard.
