Hello grandgift_hk -
We have not been able to reproduce an issue with browsers when attempting to delete images in an account, so it remains unclear what may be occurring for you. I suggest that you file a support case with us that includes your browser and operating system information as well as a few examples of images where you have encountered this issue and a full description of what occurs (including the text of any error message you might see) so we can take a look into it for you.
