Home → FAQs → Image Uploader - Bulk Active X/Java → Why do only some of the images I am selecting have thumbnails?
For the Aurigma Bulk-Flash uploader, if the images selected are very large in size, Adobe Flash Player has a mechanism in place to prevent an "out of memory" condition, so some thumbnails may not be rendered among the selected files to be uploaded. Instead, a generic icon will display. This is normal and expected and most likely to be seen when PNG or BMP files have been selected (due to their large sizes).
