One thing I always missed in WordPress is the ability to select the size of the thumbnail that’s generated every time you upload a picture to your blog. The default size is quite small, sometimes you may want it, for example, to be as wide as the page, without needing to scale the original pic down in HTML with width=”xx”.

I’ve found today the imagesControlSize plugin by aNieto2k, that allows you to select the thumbnail’s width when uploading an image (the height is calculated automatically, maintaining the aspect ratio). Works great.
