I may have stumbled across a partial solution, but it doesn’t allow you to specify an image size so much as it simply displays the image as large as possible while still fitting on the user’s screen.

Please understand I am relatively new to WP and prefer to use plugins over editing php files whenever possible. This may also only work in specific circumstances, as the prettyPhoto plugin appears to be integrated into my current theme, rather than installed as a discrete plugin.

My issue was that linking to the original image displayed it at its full size, which is seriously problematic for large images.

This is what worked for me:
Make sure you have the prettyPhoto plugin installed.
Add the image as normal to a post, linking to the media file, then edit it and go to the Advanced Options section. Enter “prettyPhoto” (no quotes) in the Link Rel field.

That’s it. Worked for me. Hopefully it will help someone eles.

I am also having the “login page just reloads” problem. I have two different installations of WordPress on my site and I access them from home (using Firefox) and from work (using IE). One of my wordpress installations works fine no matter where I am, the other works fine at home. But when I try to login from work, the page just reloads. If I use the wrong password it tells me so, so there’s no point in resetting the password (it works at home). I have emptied the cache at work, but that doesn’t seem to do anythnig. I’m convinced there must be something on the machine or maybe something to do with the IP address there. Any ideas?
Nevermind, I have the same problem as above. Thanks
