I've tried to post image directly via the integrated stuff, and was told, that it's not an image.

After trying to post the link I've mentioned above, it says: "Error: the link is broken, has expired or timed out (try again), or image is invalid"

Seems like there's a bug in the thumbnail generator.

Besides, it takes forever, until the post fails.

If your connection is slow, it will have a higher chance to time out and throw an error.

Image files submitted on poal are directly uploaded to pic8 without passing through poal before the thumbnail is generated (based on pic8 shortlink).

This can't be the reason. Posting the pic8 link as the image source also fails.

You should have mentioned it then.

Some images have the wrong extension and will confuse poal's detection code.

Does it work if you try to upload an image file or link (that fails on poal) on pic8.co?

I've mentioned it:

However, now I've tried it in my own test channel, and it worked. So it may be, that there is another bug with the form, which causes problems when you first wanted to upload some pic, and then changed your mind to specify a direct link to the image. But this may be just a UI issue. Not sure, if it qualifies as a bug.
