When pasting an image from the Windows clipboard into a Jira issue (new issue view), the image is accepted and a preview is displayed. However, when saving the issue, Jira shows the following error:

Since editing the new issue takes time and involves several images (some from clipbord, some from filesystem) I would appreciate the error immediately when pasting the image instead of showing a seemingly correct preview and cancelling all of your work in the end when pressing the save-issue-button.
Therefore: Expected Behavior:
Jira should validate the image format immediately upon paste and either reject the upload with a clear error message or display a warning that the image cannot be saved later.
