Weird Image Error

[thetuningspoon]

I have email error notifications turned on for one of my recent ProcessWire sites and have been receiving the following error alert:

Error: 

Call to a member function height() on a non-object (line 292 of /home/teachct/public_html/wire/modules/Process/ProcessPageEditImageSelect/ProcessPageEditImageSelect.module)

I'm not sure exactly where this is happening because the client has not reported any visible issue. However, I'm wondering whether this might be a familiar error to anyone (or something that might make sense to Ryan )

Thanks!

This process is used in Wysiwyg to select and resize the image.

The error indicates that it didn't find the image object and thus have no height() method as it would have. Strange here is the the previous line does seem to work.

Most likely there is an image in the system that isn't quite valid in format and so the resize failed. But it must be close to valid, because the previous checks apparently missed it. My guess is a corrupted image.

Thanks guys. I haven't received any more notifications for a while, so I guess I'll just keep my eye on it and see if the client reports anything.
