Asset has been uploaded manually into the DAM using Upload process. After uploading the asset to DAM some default renditions are getting creating but our issue is not about renditions.
Our Exact Issue: Why in AEM 6.4 for thumbnail view of image it is using 319*319 rendition path instead of renditions/original path which is working fine AEM 6.2. Is there any kind of service packs we have to install?
When we check in DOM, i see that image path of thumbnail view in card view/list view/column view is something like below
If you are asking about the Asset Card view display in the Touch UI then yes it should render a thumbnail of 319X319 size. Why do you would like to use original image for card view display ? Isn't that going to be a performance issue. If in 6.2 it was rendering original images then it should be a bug because it does not make sense to display original images for card view.
On 6.2 also you should see a rendition only instead of the original image. something like 1280.1280 one or the one whose width is nearer to given width. I just figured out that as soon as you upload the image on 6.2 , for a moment while the image is being processed, it shows you the path of original because its still creating different renditions. Once the renditions are created, and if we reload the page again, it displays the 1280 rendition.
or while uploading image to 6.2, you must have disabled the update asset workflow launcher.
See the comparison in the getThumbnailUrl method in 6.2 and 6.4
