Post-processing of the image likely failed because the server is busy

We came across this error for the first time recently when a client emailed over an image he was having trouble uploading to his site.

A bit of research showed this warning can be caused by quite a few issues – but an easy one to rule out right away is whether your filename contains any punctuation marks.

It turned out the apostrophe was causing the issue and renaming the file solved the problem.
