I am experiencing problems with the media size in Twenty Eleven Theme.
The theme tells me to size my Featured Post pictures at leas 1000 x 288 but unfortunately I can't upload that large pictures as my only option after the upload is either:
Thumbnail (150 × 43)
Medium (300 × 86)
Large NOT AVAILABLE (gray dot)
Full Size (584 × 168)
Any idea what is going on? I have tried to set the media size to over 1000 x 288 but I'm not able to.
I'm using the Twenty Eleven theme with Showcase at the moment.
