[Plugin: ImageFX] Doesn't work on older posts

The plugin only works at the time of the image being uploaded. It doesn’t adjust old images that already exist.

It doesn’t work if I try to upload a new image to an older post. That is where I encounter the error.

i found the same problem here. if any solutions come up i would like to know.

ps: great plugin! thanks!

I can confirm this issue. I emailed Otto about it on the 11th, and have got no response.
Basically, if you do the following, you won’t get an image:

• Create a Page
• Upload and set a featured thumb and publish page ( = ImageFX producers new thumbnail correctly)
• Remove featured thumb and delete if from the gallery.
• Upload new thumbnail ( = No new thumbnail created by ImageFX).

So, basically you can’t set a thumbnail publish the post/page, then remove it and try another one. You only get one shot at it per page at time of creation.
