Attachment taking 30+ minutes to upload.

I tried to upload an attachment for my Photoshop resource pack since external links aren't allowed and I waited like 30minutes and it didn't upload, are uploads always taking this long? I tried again uploading from an uploading site instead of computer and ********e uploaded in like 30 seconds. But MPGH was taking forever so I gave up.

Any suggestions?

It happens when the site gets lagged up form alot of people, just wait a couple of hours and you should be fine.
