Need more information about your setup (what version bbPress did you install and what plugins have you tried?)
This plugin will allow your members to upload images to your forum:
https://bbpress.org/plugins/topic/bb-attachments/ was working up to 0.9; not sure with 1.0
There was also a plugin to allow images in posts, but it didn’t offer any hosting:
https://bbpress.org/plugins/topic/allow-images/
I only tried those two plugins you mention with no luck.
Im using bbPress 1.0.2
Are there any other solutions?
The one that is probably closest to what you want is bb attachments, so an option might be to fix that one to work with 1.0.2. There is no plugin like that that works with 1.0.2 that I know of.
https://bbpress.org/plugins/topic/allow-images/ works in 1.0.2 and in trunk (is a very simple plugin). Your users must use the right syntax of the img tag <img src="http://the-url.com" />.
Looking for an image uploader not just a link
