[edit] Why so many edits to this image page?

I uploaded the screenshot and could not see it: only a blank spot on the page. When I linked to it in the project image gallery, I saw an empty frame of the appropriate size (144x144px). I assumed it was a WP problem and fooled around several times trying to re-upload the image. Clearing the browser cache, quitting, even rebooting,waiting several hours (hoping WP would get right) all had no effect.

Turns out it has nothing to do with WP; I cannot see the image (as I originally uploaded it) in my browser (Mozilla 1.2.1 for Macintosh OS 9.2.2) even when I open the file directly from my local hard drive. Oddly, I can see it with other browsers. (!) I took the screenshot with Ambrosia Snapz Pro 2.0.1, which seems to add some nasty kiss-of-death scrap of code to the image which is preserved through edits and saves in PNG format; I tried Adobe Photoshop 4.0.1 and GraphicConverter 4.0.8. Nor does it seem to matter which kind of interlace or prefiltering is used. (!!) However, saving into GIF works fine. (!!)

I finally hit on the idea of opening the bad file and copying the image out (cut-and-paste) into a new file; this takes the bitmap of the image while leaving the KoD nastiness behind. This laundered image file displays fine both locally and after upload to WP. (!!!)

Even more bizzare: Other screenshots taken with Snapz Pro and saved directly (presumably with the nasty bit included) show up fine in Mozilla; but it's not only this one image that gave me trouble, but three in a row, all similar, but slightly different. (!!!!)

I'm fortunate that it was my browser that had the bug; if I'd seen the screenshot I'd have charged straight ahead and it might be ages before a frustrated reader had reported not being able to see the image(s).

You may be able to explore this bug by looking at older versions of the upload using the page's history. Please let us know what you see.

Recommendation: Workaround this problem proactively: Open all screenshots in an editor, copy the entire image, and paste into a new ("virgin") file/window, then save in PNG format; then upload to WP.
