I thing there is still confusion about the images in the upload window for the profile album... These pictures that appear on the pop-up windows when we upload to the album...
the "Uploads not utilized within one hour will be deleted" applies when we use the upload function prior to submit (i.e. to effectively save the pictures in the album). What it says is that if a user starts uploading but does not complete the process up to save in the album photo, the picture will not be available after an hour for transfer to the album... However, it is right that whatever picture was once uploaded in the 'intermediate' window are still there.
Now, regarding the pics remaining in the album upload window, I am not sure they are counted in the user allowed quota for images. We did the exercise of counting the space taken by these pics with some other users, and it was way over the space effectively taken (mentioned allowed space available).
The thing to consider is that this quota is taking into consideration not only the images from the photo album but also from the attachments posted in some other posts... and most likely the profile pic, the avatar and signature...
In any case, the exact situation has to be reassessed as, so far, it is still not clear. But I would encourage the users who are confused with the amount of pics in the uploading window to check first effectively how many pics they have effectively active in the forum, either in albums photos, attachments, pics/sig/ava, and what size these amount to...
So... before adding to the issue, I would suggest everyone who has a problem to start taking note of the above (effective space taken, pictures in album photo/attachments...), so to provide some useful information to Dai when he will be back
