This doesn't happen all the time but it seems to happen with 1 every 10 book images I post. I'll use the exact same dimensions when uploading an cover image. For example, if I go to BN.com to get the cover image, i will always click to save the largest image possible to upload.  Most of the time it goes through perfectly, everything gets approved and you can see the image everywhere.

However sometimes the image will only show up on the My Account WL but not for the actual book link, if you click on the link or look on a wishlist it still shows as no cover uploaded.  I have to go into edit book data in order to re-add the picture for it to show up everywhere else.   When the images get approved are they not getting approved for all links? Are they only getting approved to show up in certain places?

I think it is a image size issue. That happened to me once or twice when I was getting and uploading images from Amazon. If you click on Edit Book Data for one of those books, and look at the bottom, I bet you will see that the image is there in the small size, but not for the larger sizes.

I don't know if there is a way to fix it except by uploading a larger image.

I don't get images from Amazon anymore ... now, I always scan my own covers and upload that image ... its always big enough.

To be absolutely sure your book will be uploaded to all sizes, it should be a minimum of 290-325px X 500px  If your book is a wide one, that would be upwards of 350 wide, when you crop it to 500 tall, then go with the smaller width of 325ish. I have seen 500 tall that are narrower than the normal 290-325px, but only a time or two have I seen them over 325 wide (I was surprised because they actually went over the title text).

I hope this helps, but if you need more help feel free to ask myself, or any other member with the BI/BDC icon (Book Image Team)
