I am using the instagrate plugin. It takes images from instagram and posts them automatically. Works great. It even lets you select your image and select it as the featured image.
Now on the Twenty Eleven theme that means a new banner for each postbeacuse the featured image becomes the banner.
However the problem is this:
The image snagged from instagram is 640 x 640.
The 2011 theme lets you set any photo you want to your featured image but it only uses the photo if it is 1000px.
I am looking for a way to have continue using the default 1000 x 288 for the banner (header image / featured image) but when the photo is less than 1000 in width it will stretch it and use it. I still want the photo chopped at 288.
Any photo no matter what size (1000 px or shorter) will still appear when selected as the featured image. And that the header image (although stretched) will keep the prober ratio for height and still be cropped at 288.
