The image processing for UBB.threads has been considerably updated since version 7.6.0 (which you're currently running).

It can take and process a standard sized (example: 12MP-16MP) smartphone photo and reduce the dimensions and file sizes for you on the fly.

[Linked Image]

The result will be an attached post image which uses much less storage on your server, and "costs less" to transfer for each page view.

I would highly recommend that you stay away from photobucket for a few simple reasons:
1) uploads to photo bucket mean that you never have control over the photobucket-linked-content your users post. And it could go away whenever photobucket chooses, creating incomplete posts and broken links.
2) if you ever decide to jump on the HTTPS bandwagon which most of today's internet is headed towards, be warned that photbucket still doesnt support https, and you are linking to a 3rd party for your content (see also #1). a future UBB.threads 7.6.x feature which is being worked on, will be to check if your main domain is on https, and then only allowing inlined images from your own website, and others who are also https -- meaning that photobucket's insecure http urls will not be displayed as images, but only as a url link to the image. This is intended to preserve the https validation of your pages.
3) users leave your site to create and account (and upload, manage...etc) at photobucket. a user can also violate the terms of photobucket and have all their account photos deleted, thus removing valuable content from being used on your site. a user can also choose to have their photobucket account deleted, with the same results. if a users requests that your delete their account from your UBB.threads forum, you can remove their account, but keep all the content that was created, and label the user as "Anonymous."
4) photobucket is not mobile friendly. if you have users with android or iphones, they may just ignore trying to attach any images at all. (see also #3)
5) if you do choose to manually manicure/curate your attachment folder for NSFW/unrelated forum attachments, you absolutely wont be seeing any of the linked items linked from photo bucket.
6) Perl/CGI scripts... A quick google search returns many results. These were within those results: (A), (B).

The attached image processing code for UBB.threads 7.6.1 is basically written and done already. The Control Panel page settings for this new code are being written with as much time as I can put in to it -- June was an awful month for my productivity due to picking up a new 6 week puppy at the beginning of it. She's getting better and sleeping for longer periods of time now, so I've been able to jump back in to some UBBT programming over the last week. (translation: im looking forward to getting this new code finished up, and in to everyone's hands as soon as I can. I've been looking forward to it since May).
