How can i change the number of images in my wordpress content

Hi all.

When we upload one image in our wordpress upload we can find the same image but in 16 diferents sizes (that is a lot of space). How can we work with that to have only a few or one?

Thanks

Set the sizes you wish to use in the modules settings for thumbnails; choose your modules and layouts to only use certain sizes, like a small, medium, large. For instance, use just ONE size/module for sidebar and secondary sections on front page = one size. Etc.
