Is there something that needs to be 'rebuilt' in order for this change to take effect on existing images?

Nope. The only reason you would need to rebuild is if you changed thumbnail dimensions. In that case you would need to rebuild your thumbs to generate new ones with the new dimensions. -
The size of the image (.png) when I uploaded it was 569 x 960 pixels.
The Attachment Manager originally had 620 x 280 (max width x max height).
I changed it to 800 x 600 but the image is still displaying as 472 x 280.
Could the problem be that the Maximum Filesize is set to 20000?
What does vbulletin do to images that are under the max width and max height but near the Max filesize?Comment

Oddly, I just noticed that my maximum filesize for .png is 20000 bytes but the uploaded image is 27,900 bytes.
Why would that be?Comment

Changing the dimension limits will not affect any existing images. The existing images are not automatically changed to fill the new max dimensions.Comment

So when the image is uploaded, for the first time, it is re-sized and stored in the database at that new size?
Also, I'm curious, as to why the .png that I uploaded was converted to a .jpg. I noticed that when I went to edit the post I saw the extension had changed from .png to .jpg.
Thank you.Comment

If any resizing or thumbnail generation is involved, then the format might change. These generated images are either JPG or PNG depending on your server configuration.
In my testing, post attachments are not automatically resized if they exceed the dimension limits. However, they are resized for the purpose of thumbnails if you have those enabled.Comment

Isn't the purpose of the Max Width and Max Height to automatically resize images that exceed the dimension limits?Originally posted by Jake Bunce View Post
If that is not the purpose, can images be resized that exceed specified limits?Comment

That option can be enabled:
Admin CP -> vBulletin Options -> Message Attachment Options -> Resize Images
This doesn't work in my testing. As that setting says, resizing may fail due to server configuration.Comment

Hello anyone, does resizing images work for you?
Does anyone know what server configurations are necessary to make this setting work?Comment

I'm still trying to figure out what is necessary to make image resizing work.Originally posted by rnmcd View PostComment

I don't know what those settings are. I will ask the others about this.Comment

In the vBulletin Options
vBulletin Options > Message Attachment Options > Resize Images
If an image is larger than your maximum allowed dimensions or filesize, an attempt to resize it will be tried. This may fail if the image is too large to be successfully processed or if the image type is not supported for resizing. When this option is enabled, you should limit the Attachment Input options above to one, otherwise the uploading of multiple large images by one user could strain your server.'
You're server will need either GD or ImageMagick for this to work.Comment

Should this image resizing work with both uploaded attachments as well as URL attachments?Comment

I checked to make sure that I had all the admincp settings correct and it appears that I do.
I also have both Imagemagick and GD.
But for some reason when I try to upload even one image that is larger than the dimensions specified in my Attachment Manager I get an 'image exceeds limits' message during my attempt to upload.
For example, I have my .jpg Max Filesize set to 100,000 bytes (97.65625 kilobytes). I tried to upload an image that was 101 kilobytes and I got the 'image exceeds limits' message during my attempt to upload.
Any idea what could be going wrong? The image in the example was only about 3 kilobytes larger than the maximum size limit. Should it have been able to be resized?
Thanks.Comment
