Playing on Win7, the performance is very slow and choppy, with mouse lag. Also the windows bar appears in the upper side of the screen, as you can see in the attached image.

Aaand my attachment doesn't show up either...

It seems like the problems only occur on the integrated GPU, which is still far more powerful than the one I played the game on back in the day, but whatever. I still remain with the issue of not being able to attach images to a post. And yes, they're smaller than 2MB. Anybody know of a fix?

Make sure the extension is all lower case, e.g. .jpg and not .JPG.

The file was called desp1.jpg and I changed it to desp.png. Let's see if it works.

It didn't. Thanks for the reply anyway.

Looks like there is still a limit of 500000 bytes per image. The error notifications seems bugged. I only got it when the image was just over.
