Both the lite and the full-featured editor for MOSS can insert images in a discussion board post. By default, the editor is configured to work with the libraries from the current site, so if you have a picture library, it will be available in the editor's image manager dialog. If the users have write permissions, they will be able to upload new images in the library and insert them in a post.
Discussion boards fall into the list scenario of the RadEditor for MOSS so any list settings you apply in the RadEditor will also be applied there.

I do not understand what do you mean by emailing images. Could you please explain in some more details the functionality that you are asking about.
Thank you.

If you want insert in directly you'd better take a look at Sharepoint Rich Text Boost, which allows users insert image directly.
Hope this helps

Hi, I mean its not OOTB, but you can execute the javascript function UploadAttachment(); in EditForm.
If you want the Attach File Button in the ribbon you have to add a custom action
<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
<CustomAction Id="DiscussionAttachmentAction"
Location="CommandUI.Ribbon"
RegistrationId="108"
RegistrationType="List"
Title="Re-Add an Attachment Button to Discussion Boards">
<CommandUIExtension>
<CommandUIDefinitions>
<CommandUIDefinition
Location="Ribbon.ListForm.Edit.Actions.Controls._children">
<Button Id="DiscussionAttachmentButton"
Command="AttachFileDB"
Image16by16="/_layouts/15/$Resources:core,Language;/images/formatmap16x16.png?rev=23" Image16by16Top="-235" Image16by16Left="-235"
Image32by32="/_layouts/15/$Resources:core,Language;/images/formatmap32x32.png?rev=23" Image32by32Top="-409" Image32by32Left="-409"
LabelText="$Resources:core,cui_ButAttachFile;"
ToolTipTitle="$Resources:core,cui_ButAttachFile;"
ToolTipDescription="$Resources:core,cui_STT_ButAttachFile;"
TemplateAlias="o2" />
</CommandUIDefinition>
</CommandUIDefinitions>
<CommandUIHandlers>
<CommandUIHandler
Command="AttachFileDB"
CommandAction="javascript: UploadAttachment();" />
</CommandUIHandlers>
</CommandUIExtension>
</CustomAction>
</Elements>
Thanks and regards,
