Hi everyone!
Yes, the site is still having issues. You will see 504 errors or something similar. Or if you click on a thumbnail and the wrong picture(s) are showing.
To "possibly" fix the thumbnail issue, go look at a gallery. Then choose the option of One Page instead of Detailed View.
GIF pictures : Since the pictures are so large this will cause the upload(s) to time out. And you will see an unknown error. The problem after that is, you can't re upload the picture because the site thinks the picture does exist.
As for the site running slow, the IT guys and the site owners are aware of the problem. I haven't been informed when this issue will be looked at or resolved.
