How can I make an image smaller?
[img=100x50]link[/img] and [img widht="100" height="50"]link[/img] surprisingly don't work.

If my information is correct, our vBulletin doesn't support resizing at all.
You need to upload it to an image hosting site in the desired size.
And then post the link to the image here, already in the desired size.

I replaced the image, reducing its size by half (the width is now 960 instead of 1920).
It looks good now.
