Category image size

This must be simple I am sure.....How do I get a Category Image to be the width of the right hand side of the page (ie to the right of the category list)?

I have tried various settings in Admin/Configure/Images/category icon image width and height (currently set to 800x 280). I have even tried resizing the image prior to uploading, but cannot get it to display bigger than eg Little Darlings image.

I need it to stretch right across even if it goes further down the page.

thanks

here is the image for your cat:
179bfb07b9c99cacdcb075b4c33ec7f1.image.373x280.JPG
Dimensions373 × 280File size15.48KBMIME typeimage/jpeg

the listing div is 650px wide. try resizing the image to 650px wide or just under.

I don't understand this size. I deleted it and re-uploaded the original, which is 640 x 480. Is there some setting in ZC that cna change this?

thanks

did you check your settings here?

Admin>Configuration>Images>Subcategory Image Width
and
Admin>Configuration>Images>Subcategory Image Height

Ah!! Thank you - it was set to 200 x 160. I changed to 640 x 480 and now see the image right across.
I had wrongly thought it was the Category Icon Image width and heigth. Many thanks - I knew it should be simple!

Under admin there is only includes, nothing else. ???
