Error Message: Exception Message: Expected response code 200, got 400

Since the app worked fine for me, the issue didn’t seem to be with the code. After some frustrating, unproductive troubleshooting, I finally built a file upload mockup and ran the $_FILES array through Zend_Debug::dump(). I discovered that while Firefox reports the MIME type of a jpg as “image/jpeg”, Internet Explorer reports the MIME type as “image/pjpeg.” Thanks a lot, Redmond.

As it turned out, the problem occurred when I tried to set the upload content type to “image/pjpeg”:

$fd = $this->_service->newMediaFileSource($photo["tmp_name"]);
$fd->setContentType($photo["type"]);

I resolved the issue by adding a test for the pjpeg MIME type before setting the content type. The new code looks like this:

/** Resolves issue where IE changes jpg MIME type to image/pjpeg, breaking upload */
$photo["type"] = ($photo["type"] === "image/pjpeg") ? "image/jpeg" : $photo["type"];
$fd = $this->_service->newMediaFileSource($photo["tmp_name"]);
$fd->setContentType($photo["type"]);

The code snippets above come from an image upload helper method that I built (borrowing heavily from Cory Wiles) to make working with Zend_Gdata_Photos a little easier.

If you’re having similar problems uploading images, regardless of the method that you’re using, check that MIME type and see if that’s not the issue.

IEs4Linux is the simpler way to have Microsoft Internet Explorer running on Linux (or any OS running Wine).

I recently purchased a new Dell 1420n with Ubuntu 7.10 pre-installed. One of the first things I wanted to do was install all of my development tools, including IEs4Linux. What should have been an easy installation turned into a nightmare. I kept running into python errors that aborted the install. Once I finally got the application to install it was unusable. The IE toolbar was missing, including the address bar, the application would frequently crash, and I experienced maddening display bugs.

Apparently the blank screen bug has been a widespread issue. Sérgio has addressed it on his blog and pushed an emergency release of IEs4Linux, version 2.99.0.1, to resolve this issue only.

That’s all well and good, but I still had the python issues to deal with. What finally worked for me was to install IEs4Linux with the –no-gui flag, like so:

$ ./ies4linux --no-gui
