Generating Images from image styles in drupal 7

Question

I'm just getting accustomed to the changes in drupal 7, I've created a number of nodes that have an image field. The nodes were created as dummy content from the Devel module. I then created a view, added a number of fields, and chose my image style as a formatted for one of the fields. The only thing I can't figure out is how to get Drupal to generate the the images, I tried re-generating the dummy conent, but it still does not create the thumbnails.

Any Ideas?

Answer 1

Are the folders where the images go writable? Also check the tmp folder

Answer 2

image style images should be dynamically generated as needed. Are the links to the images being formed properly? They should be in the files/styles folder
