Hi Neil,
Although you can't attach pictures like you can here in the Forums (using the "Manage Attachments" button), you can use the [img] bbcode link to specify a URL. So, if you have images in the AikiWeb
image gallery, you should be able to reference the images from there.
If you've run out of space in the AikiWeb image gallery, the easiest way to double the amount of images you can have (as well as a lot of other advantages) is to become an
AikiWeb contributing member.
Hope that helps,
