We recently upgraded our application from Image Uploader 4.0 to 4.7.
We are using the "User Quote" mode of the control.
My clients start complaining that now it is taking a very long time for the control to populate the pane with the list of files in the selected folder.
The users of my application is uploading thousands of images, 60 images at a time and their folders can contain more than hundreds of images.

I saw a similar post in the Forum before and your response was that the next version of the control will have some fix for this issue. Unfortunately the time is something we do not have and we need the fix as soon as possible. If it is possible to get a hot fix, please, let me know.

Thank you in advance and regards.

Thank you. I will do it immideatly.

Thank you. We got the new version and installed it.
It solved (partially) the performance issue when loading the pane that is displaying images. Some of our users report visible improvements; some still complain that it takes up to a minute or two to populate the pane.

But now we are facing a few other issues:

1. When I select files, checking them off in the “Files” pane, it takes a few seconds for check box to appear on the screen. My users uploads thousands of images daily and a few seconds delay for each checked image amounts to a considerable time loss for them.

2. Since my users upload a large number of images ( 1 million a month), they select 30 – 60 images at a time to upload.
Now here is another issue: when the “Upload” link is clicked, the screen appears that displays the upload progress. It takes only 10-20 sec for the control to send the images to the server, and then it takes from 2-4 minutes to wait until “Success” message appears. That is extremely slow and I afraid to put the control to production, as I foresee the storm of complains from my users.

Below is the code that is setting up the control. Please, advise, if I could do anything to improve the performance.
