To personalize with images the Web of connection and registry of clients would be brilliant.
Your customization page is already customisable with html.
To add images in it, they must be hosted on worldspot.
Which you can do with this forum (as a workaround)
For example, the image url below link would be
<img src="/forum/index.php?action=dlattach;topic=17.0;id=1;image">
In the near future, welcome page will have a wysiwyg editor with image uploading.
Paypal will be proposed next. Of course...
