Corrupt Image

Could it be this: #270 ?

The question is rather: Do you have mod_deflate or similar enabled in your webserver?

What you can also try: Compare the HTTP headers sent when you directly download the image you saved on the server to those when you use send().

I can not help you with debugging HTTP headers. Each and every request and response has HTTP headers. So it's the first thing that comes to mind if there's a difference between saveAs() and d/l and send(). If the content is the same it can only be the headers that differ.

I don't know either. It sounds very weird that you say saveAs() works while send() does not. Both use the same file (temporarily saved on disk). The one only copies the file to your saveAs-location and the other sends the file.

Try to call saveAs() and then send() the file for download and then compare the binary content. It must be the same.

I'm sorry, but I have no further ideas.

Hmm, while it looks a bit hacky to me - if it works I'd say it's fine.

I'm sorry, that I can't offer more assistance. TBH I myself never used wkhtmltoimage and only added this as per request of another user. All this is vulonteers work, you know, so I can't guarantee that everything always works as it should and I don't have the time to fix each and every possible problem immediately.
