Image Auto-Resizer is a plugin for MyBB 1.8. It auto-resizes uploaded images so that they do not exceed a stipulated maximum width and height (defaulting to 900 pixels for both).

Via the Admin Control Panel (ACP), it is possible to:

• Set the maximum image height and width for image attachments.
  
• Resize all preexisting uploaded image attachments, by clicking "Go" beside Tools & Maintenance -> Recount & Rebuild -> Resize Uploaded Images.
  

Installing

1. Download.
   Download an archive of the plugin's files.
   
2. Copy files.
   Extract the files in that archive to a temporary location, and then copy the files in "root" into the root of your MyBB installation.
   
3. Install via the ACP.
   In a web browser, open the "Plugins" module in the ACP of your MyBB installation. You should see "Image Auto-Resizer" under "Inactive Plugins". Click "Install & Activate" next to it. You should then see the plugin listed under "Active Plugins" on the reloaded page.
   
4. Configure settings.
   Navigate in the ACP to Settings -> Plugin Settings -> Image Auto-Resizer and configure your preferred values for the settings.
   
5. Resize preexisting images
   Optionally (but recommended), run "Resize Uploaded Images" as described above.

Say bye to oversized images, long loading times and huge used space for image attachments

Nice tool. :thumbsup

Very interesting plugin, I remember there used to be auto-resize plugin in past but that became outdated.
I have a question, how will this plugin render images for mobile? Will it be the same or different?
Basically, does it supports srcset as it will vastly improve image sizes for different devices?
Very interested

Right now, the plugin is very basic: it solely resizes oversized uploaded image files on disk with the aim of saving disk space - replacing the original image file rather than creating a new one - so, it currently doesn't provide alternative image sizes, and thus, no, it doesn't currently support srcset. We could say then that its only effect on rendering (on mobile or any other device) is to (potentially) offer the browser a smaller-sized file than was originally uploaded.

The idea of supporting srcset is an interesting one though... maybe in a future release?

Very useful plugin, I like it. I would only suggest in future releases, to add compression, that will also compress images after they being resized.

Yes, that's a good idea, which @Eldenroot had too and has added as GitHub issue #3: Optimize image to reduce size.

I've added GitHub issue #5 for this in case you want to follow any discussions that might happen there: Generate different image sizes and support the "srcset" img tag attribute.

My forum has a lot of images in attachments, many of them are from smartphones with high resolution, so the size of photos is quite a lot... with this plugin I have saved almost 7 GB, now images use only 11 GB, before it was 18 GB, so I am happy and I do not need to buy extra space on my webhosting.

Awesome, there can be a setting that can enable this feature
With Image compression, this will be a great feature.

@effone is working on few enhancements maybe soon, we will see
