Similarily you may have to insert the complete path to html pages you referenced in links although it is easier to just put in the full internet path when creating the link. Once you put in the internet paths the links and images will not work unless you are on-line. If you embedded images in the description this will not appear. You can create a little tiny image file to reference in this box or chose an interesting animated GIF from somewhere on the internet. Use an image processor such as Paint Shop Pro to crop the image to just include your item.
Bad pictures are probably worse than no picture.
Use properly exposed pictures. Select SAVE-AS and select .jpg file format. Click options and select compression level 64. The pictures in hampedia are stored with this level of compression. Hope this is helpful.
