Not sure if this'll be of any use to anyone, but I'll post it anyway.
I've been having minor issues with Chrome for a few months now, generally just being rather sluggish and causing problems with my Photobucket images. I thought it was the browser just filling up with the usual crap, but clearing out caches, history etc, didn't seem to make any difference. So I just put up with it and carried on.
I had noticed that if I created a new profile in Chrome, things went much faster, but I didn't want to delete my old profile as it means losing all bookmarks, history, extensions and such like, and having done that in the past it can be a bit tedious configuring everything to get it back the way it was, there must be another way.
Today (08/06/2016), by accident, I found that other way. I was looking through my Chrome profile folders in windows explorer and for some reason, I decided to delete everything in the cache folder. I didn't expect it to make any difference because this folder should be cleared out when you clear out your cache via the browser, but to my great surprise, when I fired up Chrome, browsing was now quicker, and when I went to look at my pictures in Photobucket, everything was back to normal and I could see my images at their full size again, whereas previously everything had been reduced to a maximum size of 1024 pixels and my links to the full sized pics weren't working.
I can only assume that for some reason when I was clearing my cache via the browser, it wasn't deleting everything (or anything) in the cache folder. I have checked it since, and it is clearing it now, so perhaps something got corrupted somewhere, I don't know.
But if anyone is having a problem like I was with Chrome, it might be worth going into your profile cache folder and manually deleting everything in it.
Here's how to find the folder in windows explorer...
C:\Users\*Your username*\AppData\Local\Google\Chrome\User Data\Default\Cache
If you can't see the AppData folder, you will need to switch on the show hidden files and folders option. To do that go to Control Panel >> Appearance and Personalization >> Folder Options, in the Folder Options dialogue box, click on the View tab and in the scroll window, click on the Show hidden files, folders and drives radio button to switch it to on, then click OK. The AppData folder should now show in windows explorer.
