Question Images in external hosting

Hello, wanted to know if you can host images on external servers (imageshack.com, postimage.org, flickr.com, etc.), since the kunena hosts on my local server and I have no place on the disk.

What I understand from your question is that you are asking that, when someone wants to upload an image (or some other attachment) and insert it into their forum post, they use the Add File button. Am I right in understanding your question so far?

When people use the Add File button to attach an image in their post, the image is uploaded to your site. There is no "configuration option" to allow people to upload attachments to a different site.

You can use images stored on other servers with the IMG BBcode tag. If those images are stored on places like ImageShack or Flickr, you can include them in your forum with that BBcode tag.

Because the attachment Add File button is designed to upload attachments to your server, you have two options:

(1) Talk to your webhosting provider about getting more storage space for your site; or

(2) Change the Kunena program to store attachments somewhere else.

The first option is probably the cheapest option. Many hosting plans offer lots of storage for very little money. You can even buy hosting plans that offer "unlimited" storage for a reasonable amount. In the end, the decision about which is the most cost-effective solution is up to you. I hope that some of this helps.

Is so hard to create a plugin to auto-import images on postimage.org for example?? It sucks. phpbb can do that, why kunena can`t?

I don't know how difficult it is to write a plugin to automatically retrieve images from some cloud storage (like post image.org) because I have never written a Joomla plugin before. I could be wrong but I thought this was a question about how to upload attachments to a cloud store using Kunena.
