Magento image not showing on backend when uploading

Possible reason for some images not uploading properly in the backend and only showing description is because they are not allowed to be modified and Magento tends to use a function for file compression and caching. I have fixed the issue on the history page and made the image available, but will look for broken links and images.

The workaround for this issue (the error should appear under the image for a brief period of time when uploading) is to rename the file and upload it again, and also to upload them one at a time if possible, or you can try less images at a time. Just make sure it does not violated any image copyright issues.

The other problem might be your image that needs a chmod 777 for the write permissions.
